2 edits |  Tips for Running VoIP from a Wireless Connection
collect the answers to my own frequently asked questions on the topic. I must state
up-front that none of this information comes from me. I am also sure that I have missed a lot. Hopefully all of you can help fill the gaps. The content below is only the result of my research into postings of other forum members. So thanks to my predecessors and thanks to those who blessed us all with their pearls of wisdom.
Why would you want to use a wireless connection with VoIP?
1. You may be sharing your home Internet connection with a neighbor
2. A wiring constraint in the space where you want to put the VoIP ATA adapter
3. You want to take advantage of a wireless hotspot with your VoIP
4. Your hotel only has a wireless connection available
5. You just want to prove you can do it
6. You have nothing better or more interesting to do with your time
7. You want to get your geek fix for the day
...
So far I am aware of the following ways to run VoIP from a wireless Internet connection:
1. Use an Ethernet Wireless Bridge
2. Use Windows Internet Connection Sharing from a computer with a wireless adapter
3. Use an altered Wireless Router
4. Use a softphone (VoIP software)
5. Use a wireless VoIP Phone
Here are some general notes about wireless connections and VoIP:
said by stevech1  :wireless LAN is transparent to VoIP. The only issues are those common to any wireless LAN setup: choosing an uncongested channel (1, 6, 11) and assuring you have a good signal so that a reasonably high data rate is achieved. said by gnexus :The quality will likely be rather variable, but it will certainly work ok. It's the same quality issue deal as with cell phones. The only issue is firewall traversion. You should set the SPA for a worst case firewall situation using STUN, even if you don't need it for your home network. If it works good like that at home then no setting changes on the road would be neccessary. If use of STUN creates problems on your network then you would have to disable it and then reenable it for travel. Normally STUN is used w/o probs. Through quotes from other forum members I will try and explain each option.
1. Use an Ethernet Wireless Bridge
said by rizzo2dial :I've never had any success in bridging wireless and ethernet network adapters, but I've been 100% successful in using ICS to connect my P8 DTA to my laptop's ethernet connection w/ the laptop's wireless connection ICS enabled. said by prestonlewis :I've used a wireless connection from a router to a bridge and connected a SIP device to the bridge without any problems. 2. Use Windows Internet Connection Sharing from a computer with a wireless adapter
said by rizzo2dial :I've never had any success in bridging wireless and ethernet network adapters, but I've been 100% successful in using ICS to connect my P8 DTA to my laptop's ethernet connection w/ the laptop's wireless connection ICS enabled. said by rizzo2dial :1) Use a crossover cable to connect your P8 DTA directly to your notebook's ethernet port. 2) Turn on Internet Connection Sharing (ICS) on your Wireless Network Interface. Note: ICS enables a DHCP server on your notebook, where the DHCP server uses the internal IP address of 192.168.0.1. It DHCP assigns IP addresses using the scheme 192.168.0.x (where x > 1). If your wireless connection is hooked up to a router using the same 192.168.0.x addressing scheme, you'll need to change your router to another addressing scheme (i.e. 192.168.1.x). 3) After step 2 has been successfully completed, your DTA should receive a DHCP assigned IP address from your notebook and be able to share your notebook's wireless network connection (i.e. you should have a dialtone at this point). said by rizzo2dial :If you don't have a CROSSOVER cable, and if you have a spare hub or switch laying around, you can simulate what a CROSSOVER cable would do by: a) Connecting the laptop's LAN port to the switch/hub using a standard ethernet cable b) Connecting the P8 DTA to the switch/hub using a standard ethernet cable (Neither connection above should go into the switch/hub's "uplink" port) c) Don't plug any other ethernet cables into any other ports of the switch/hub! 3. Use an altered Wireless Router
said by rizzo2dial :If you travel w/ a router such as a WRT54G (w/ 3rd party firmware installed, such as SVEASOFT Alchemy), you can use that router as a wireless bridge, regular router, or simple ethernet switch. Linksys makes a travel sized 54G router too which may use the same firmware as the WRT54G; however, I've never reasearched it. 4. Use a softphone (VoIP software)
said by burgerwars :I prefer a wireless connection, even in my house. The access point is usually in the same room as my laptop. So very close. I plan on using the softphone mainly outside my house anyway, as I could just use my TA in my home. wireless may be the only choice when I'm away. said by gnexus :Occasionally you might run into a network where even STUN doesn't work. It is doubtful a hotel network would be that way, but in that case the Sipura won't work. The only solution then would be a softphone which uses X-tunnels or a similar solution, or Skype. Your best solution would be to change hotels immediately and let us know here so we can avoid that hotel chain. Good luck! 5. Use a wireless VoIP Phone
These products seem to be just entering the VoIP market. This is still bleeding edge in my opinion, but maybe it is starting to become more common.
My own notes:
> Internet Connection Sharing seems to be the one solution that people have the most success with.
> VoIP Providers that allow softphones are generally only the the Bring Your Own Device providers. Read these two topics »VoIP service with hardphone, softphone & Voicemail and »Up-to-date list of providers that have BYOD ?

| Re: Tips for Running VoIP from a Wireless Connection This topic was very important to me. I knew when I traveled that a wireless connection was probably all tha tI would have available to me. The original post was based on my research with little to no experience. Now I have some experience.
Wireless Ethernet Bridge Method:
I brought a Netgear WGPS606 to behave as a Wireless Ethernet Bridge. However late I discovered that it seems to require a fixed local IP address and doesn't want to work with the wireless network here. What a waste of time and money. It worked great from home. When I could get it on the network it worked like a charm.
So I went with rizzo2dial's ICS suggestion. In testing at home this worked great once I could change my home router's IP address scheme from 168.192.0.x. Without making this change Windows will give you an immediate error and say something about the IP address is already taken. So this method concerned me as a Plan A option because I knew I would not be able to change a business' wireless router's addressing scheme during my travels. However, I caught a break, they use a Buffalo 54G Wireless Router and it defaults to 168.192.11.x. 
So here is what works for me now...
Internet Connection Sharing from a Pentium 3 700 mhz laptop with a wireless b adapter is what provides a bridged connection to Nuvio's Linksys RT31P2 router with VoIP. I hibernate the laptop and turn off the router/ATA adapter at night and in the morning I turn the whole thing one and it all just connects up automatically without any concerns about what powers up first. The voice is great, occasionally I can hear a split second light echo of myself but it is rare and easily ignorable. The wireless b connection and physical distance (Japan) justifies this very small imperfection.
I am happy with my setup and impressed that it works so well. | |

| Hotels which offer "Wireless Only" high speed internet access sometimes have Wifi bridges available for guests.
In my experience, the use of the Wifi bridge is free; however, you need to leave a hefty deposit (tyically $100) to borrow one. When you check out, if you return the bridge, you get your deposit back.

| If I understand correctly, ICS is a form of NAT routing, and will have similar NAT related issues. However, I've never looked into the details. I also am not sure about the ICS performance, if the computer is busy.
I'd say a wireless bridge, or a wireless AP will be a better solution. Many wireless AP can act as DHCP client on either side (I used to own 2 Netgear MA102 that do) (via config).
The problem is that if the connection is already via one NAT, and you add another NAT, then the combined of 2 NAT might stop some NAT traversal solutions. And even if it doesn't, removing one layer is still better. Plus it's good to not to have the laptop on at all times for that (so it can be more useful when indepedent).
Linksys mini router, WRT54GC, has received horrible reviews, is not the same inside as WRT54G, cannot be flashed with 3rd party firmware, and is not known to work in bridge mode (this I'm not sure). I bought one and returned it, before I even opened the package, after reading the reviews. Like the poster, I also thought it was a mini version of WRT54G, and was I wrong.
Some hotels charge a substantial fee for internet connection, so unless you already need internet, this might not be economically justifable for merely a Long Distance substitute. Typical large hotel chains I found, charge about US$10. to US$20. per 24 hours. (some for free, of course, if you know which ones).
Another issue is security: if the wireless side is unencrypted, and your SIP provider is also not encrypted, then it is possible to sniff the traffic wirelessly. This might not be important for most people, but I just like to mention it, as SIP by default is open traffic. | |

| Does ethernet bridging work at all? I have a P8 DTA. I connected it with a crossover cable to my ethernet port on my laptop. The link light comes on the DTA.
I also have a wireless connection that is working on the laptop. That's what I want to attach the DTA to. I then bridge the wireless connection and LAN connection. The DTA then pulls an IP, but when I pick up the phone it's a fast busy signal. I have a feeling that the bridge isn't working properly.
I'd do the Internet Connection Sharing, but stupid Windows forces you to do 192.168.0.1, and I'm stuck with a router at 192.168.0.1.
Why is there no way to override the ICS setting? Are there any 3rd party connection sharing tools that do the same as ICS but allow you to change the IP? | |

I believe it has a free trial (perhaps 30 days). Costs $25 to register, and based on its feature set, looks well worth the money.

PocketPC with SIP software, such as SJPhone.
While you may quibble that SIP Software was already mentioned, using a PocketPC is much more portable than a PC. Also, the average reader may not realize that SIP software exists for the PocketPC - so, I'm explicitly mentioning it. | |

Also, the average reader may not realize that SIP software exists for the PocketPC - so, I'm explicitly mentioning it. I do exactly that. I've got an Axim X3i and using SJPhone and VBuzzer »www.vbuzzer.com I get a free 416 (Toronto,ON) number with unlimited outgoing calls to 416 (My Vonage line has a virtual 416 on it) so I can call friends and family in Toronto as well as my Vonage line in Atlanta from any WI-FI location, such as my local coffee house. The Axim weighs literally nothing and fits in a pocket or on a belt clip. For incoming, I have my Vonage line set to Simul-ring which includes the VBuzzer 416 number, so if my Axim is online I can receive calls as well. -- Total cost for mobility >> $0.00
Sounds is as clear as speaking into a digital recorder and using my stereo headphones, I can hear absolutely everying from the person I'm speaking to crystal clear.
According to another thread, Vonage announced they're going to give out their SIP info so we can use SJPhone with Vonage without having to get a Softphone account, which according to Vonage they're doing away with.
Link to thread >> »[Vonage] Vonage Opening It's SIP Credentials?
Just wanted to let other Axim or HP PPC users in on the mobility details... Enjoy | |

| Re: Tips for Running VoIP from a Wireless Connection said by bellagio :Your Axim setup is pretty sweet. And you are saying that the quality is very good? What do you use for a headphone or headset? Or do you just use the microphone from the PDA and just any speakers? Thanks... Just used it from a 2 hotels, in 2 different towns in Mississippi. Since 99% of the places I passed all offer free hi-speed wireless internet this will work pretty much everywhere. In the first place I got about a 57% signal from the room -- the second place had 6 access points around the hotel so I got 100% from everywhere except the elevator, where I got 88%. Pretty nice to walk around the hotel on the VOIP phone without dropping a call... Bye bye cell!!
Using the stereo headphones I use for MP3 play (Sony) I get to hear the call in clear stereo (amazing how much you really hear!!) The Axim I have doesn't allow for a headset mic so I hold the Axim or place it on a table when speaking. Callers say the quality is so life-like that both people I spoke with compared it to ''being on an extension in the same house''.
With both hotels the calls never dropped (total call time for both days was over 2 hours) and the battery on the Axim went down to around 70% both days at maximum processor speed (400 mhz).
Bottom line -- can't beat a free US-CAN phone from anywhere in the world... | |

I find amazing that it works so well. Now if Vonage will just open their SIP info I'd really be rockin'. When I was in downtown Vicksburg, MS their downtown area was covered in WI-FI ZONE signs... Wish I had tested it while walking around the historic downtown area.

| About two years ago, I was running a Grandstream Budgettone on from what I recall was an SMC 2730 wireless to ethernet bridge. The bridge was mounted on the side of a coffee can with the rubber cover of the built in rubber duckie antnna removed and stuck inside a carefully calculated hole placed in the side of the coffee can.
I connected flawlessly to the Wireless access point about 1/4 of a mile away, at a friend's house. The biggest problem I had was the faulty Dlink router/Access point that always had to be reset.
I later used the same set up on a Linksys Wireless access point with no problems whatsoever. | |

| Re: Tips for Running VoIP from a Wireless Connecti Can you just use ethernet to cable your pc to the RTP300 router?
If you need to be wireless because of distance you need to cable an access point to the RTP300 router. Access points are sold by Linksys, Netgear, DLink, etc. If your pc's internal wireless card is unstable you would need to buy a cardbus card or attach a usb wireless adapter. Most all products would work.
An alternative would be to to use your electricity wires to carry the signal using a pair of Netgear, Linksys, or other company "homeplug" products and cable your pc to the adapter using ethernet. I have used Netgear's product for this purpose.
Here is a list of manufacturers of "homeplug" products: »www.homeplug.org | |

| Re: Tips for Running VoIP from a Wireless Connecti Not sure if this will help or not, but I spend a lot of time on the road and was using a USB phone with VOIPBuster since the hotel I stay at 20 days a month happened to be in a Verizon dead zone. Worked great, but I was tethered to the laptop whenever I wanted to make a call. I just recently bought a ZyXEL wirless VOIP phone and it works great! Also, I travel through a lot of airports and many have free wireless and the phone works great in those areas also. The only downside is that the phone has around a three hour battery life but can be charged with a USB cable. It really works well and is totally unlocked so you can configure to any SIP compatible network. | |

2 edits | said by dajabon :Why would you want to use a wireless connection with VoIP? 1. You may be sharing your home Internet connection with a neighbor I'm thinking of doing this. My country neighbor (very decent guy) is about 150ft across the road. My own lousy wireless routers (at our main house) crap out over 50 ft but I can connect great to a Linksys router at the local park which is over 600 ft away so I know it can be done.
So I buy him a Linksys and we split the $40 for DSL, I set up my checking account to mail him a $20 check each month. Then I connect a VOIP adapter to my computer and enable ICS. The computer will be off when I'm not here but that's OK cuz calls will go to VM.
This will cost me zero cuz now I pay:
$28 for phone service with call waiting (pretty good)
$5 for dialup (very good)
TOTAL $33
So if I do the neighbor thing I'll get (naked) DSL and it will cost me:
$20 to the neighbor
$13 for VOIP.net 500 outgoing mins/month
TOTAL $33
It'll be less reliable but I'm not here most of the time and have a cell phone. And assuming the router has good range, I'll have wireless for my laptop (actually, I do now with my dialup but that's another story). | |

| Ok So i got vonage, i have my adapter hacked so I can either use my ATA adapter, or i can use my credentials and log into their SIP server using a SoftPhone (I use SJphone)...
Here's what i have... First I had 2 Linksys WRT54GS's setup in WDS mesh mode, using sveasoft firmware... Latency sucked dink...
Generally using just my laptop, connecting to my AP, using a softphone it would work fine... So if u have it setup right, i think VoIP is totally fine over Wifi...
Then i procedded to settup up one of my APs as an AP, and the other as a client, setup with a different subnet, and setup static routing... tried the softphone, worked great. added about 2ms of latency to the trip over the intarweb to vonage's proxies...
Now since I had 2 networks (different subnets) connected via wifi, i decided to hook up my ATA adapter to my wireless wired network (contacts internet via other AP). Bam, it worked fine....
Donno if this helps, thought id post my experience... | |

| Just a note to others: It can be done very easily.
I've been sharing a connection with my neighbor, we use a WRT54G and a Netgear WGE101 which has been the stablest bridge I've used. The interface is rather lame and it only does WEP, but it generally will run months without needing to be reset while connecting a good 5 computers on my end, plus VoIP and P2P apps.
With my Vonage service this set up ran virtually flawless for two years in conjunction with the Moto Box. We share a common wall so signal strength is good.
I will say, I've tested numerous other VoIP set ups with this set up and seemed to always have jitter and dropped packets, but with Vonage and the Moto box, it ran like a charm. Hope this encourages others. | |

3 edits | I live in an apartment building in which the owners provide free wireless internet access. I have been using an older laptop that has wireless and ethernet built in to setup ICS. The notebook picks up the wireless signal and feeds the signal to my vonage VOIP adapter/router via an ethernet cable. Works GREAT. I plug my phone into the Vonage device and the phone signal is fine. I can also plug a second computer into the Vonage device's LAN port via an ethernet cable and the second computer picks up the internet just fine.
I just got a Sunrocket Gizmo. When I hook it up the same way my vonage adapter is hooked up (using ICS) the router part of it works fine (it will pick up the internet signal and pass it on to the second computer) but the VOIP light just keeps flashing red and I get no dial tone when I plug my phone in. I tried using a crossover cable - same results. The Gizmo works fine when I go to a friend's house and use it with his cable modem - even if I put it behind his router.
Very strange - Vonage adapter works fine, Sunrocket Gizmo does not.
Any ideas? | |

| Re: Tips for Running VoIP from a Wireless Connection said by ilhy :How to use a ATA in a password protected(not security,have to enter userid and password) wireless network? That depends on how you intend to connect the ATA to the wirless network in the first place.
If you go the ICS route, simply authenticate (via username/psasword) the wifi connection on the PC/laptop running ICS.
If you don't want to be tethered to a PC/laptop, use a Linksys WRT54G (or WRT54GS) router loaded w/ 3rd party firmware which supports "Client" mode wifi connections. Such connections:
1) convert the router into a Wifi bridge (on the WAN side)
2) provide a NAT'd interface on the LAN side so that multiple "devices" can share the "Client WAN" wifi connection (at least this was how my WRT54G behaved unde Sveasoft Alchemy).
Then, with a PC/laptop (temporarily) hooked up to one of the WRT54G's LAN ports and the ATA hooked up to another of the WRT54G's LAN ports, authenticate the wifi connection on the PC/laptop (using the username/password). That will authenticate the "Client WAN" side of the router to the wifi network. All devices NAT'd behind that connection (i.e. all devices on the LAN side of the WRT54G) will now share that "authenticated WAN" connection. Your ATA should be able to work thereafter. It will also hopefully keep your Wifi connection "authenticated" 24/7 as it'll presumably be sending VoIP registration requests to the VoSP every few minutes.

In option 2, could I shutdown my pc after authentication or I have to keep it running 24/7?
Thanks in advance! | |

You only need the PC/laptop hooked up whenever you need to authenticate the wifi connection. In many places, wifi connections remain authenticated so long as there's activity taking place across the connection. With the ATA sending registration requests every few minutes, that would hopefully keep the wifi connection "active" (and thus authenticated). If you're lucky, you'll only have to authenticate once.
Some wifi systems, however, require re-authentication every 24 hours regardless of wifi activity. In that the case you'll need to re-connect the PC/laptop every 24 hours to re-authenticate.
