Rogers tells me that all voip is supported and they are not blocking ports.

I found some forums saying that portable internet (rogers WIMAX) disregards incoming SIP packets.

I can't find any information and I wish I had known this before I went and bought my PAP2T.

My softphone and the hardware will not work - I get a dial tone that runs out - no calls.

Some have said that you can use realtunnel to bypass the problem - but I cannot figure out how to get it working.

Has anyone encountered this?

thanks,

Well though Rogers isn't bocking any ports it is just the topic of running VoIP over WiMax which makes most VoIP engineers cringe, being that the packet loss is incredibly high so your voice quality would be comparable to using your cell phone in a bunker - It's fast in theory, but once you're running something that must be sustained for elongated periods of time it's not so fantastic anymore.

Now don't get me wrong, it can work, and it does - But we wouldn't be able to support it, devices or otherwise.

I'm not sure what Rogers defines as VOIP? In general, I have yet to know anyone to successfully get any VOIP setup working over 3G portable internet on a PC (portable devices like iphone are exempt from this). The SIP invite packets generally never reach the destination UA

Yes it does work as Rogers portable is my internet provider.
Mind you sound is not the greatest

Good to know! It seems things have changed since my last experience with VOIP on these network types

Rogers offers 2 types of portable internet : USB stick and modem.
I presume the packet loss would be lower with stick than with the modem especially in my case where in order to get good reception in my house I can only put the modem in selected areas and therefore must rely on a wireless router to get the signal to my laptop.

I have yet to try to make a call in the car in an area where signal would be very strong and modem directly connected to laptop.
Will report on that later.

i have got the stick to work (bell) but as soon as you turn on torrents or youtube, the voice gets all choppy ...

Hi. I have VOIP using Rogers Portable Internet. It can work great, but you have to configure your VOIP properly.

The soft phone is most likely going to be awful experience, because it does not compress the audio, nor does it handle jitter all that well. Rogers Portable Internet uploads at 32 kB/s, which should be good enough, but there are too many times when it is not.

You got to buy the freephoneline SIP settings to have a decent phone experience, and should get an SIP ATA box so you can use a good phone.

Ok, on to Rogers Portable Internet.

Some Rogers Portable Internet boxes messed with port 5060, and I would guess some still do. I know mine did. Interestingly, I cancelled for a few months, and after I reactivated, Port 5060 worked perfectly. Either way, it is not a big issue with freephoneline. Use port 5061 instead, and everything works fine.

You also need to select the G.729a codec. It is not only easier on the bandwidth, but it handles jitter much better than the other codec. You do all that, and you will have rather enjoyable experience using freephoneline on Rogers Portable Internet.

I do not blame you for not even daring to support WIMAX setups, but in my experience, the combination of G.729a, SIP and WIMAX are extremely tolerant to the crap that befalls that sort of setup. I even took it on a road trip, and as an added obstacle, I had the Rogers Portable Internet plugged into a WIFI router, and used a WIFI phone for the calls.

Surprisingly, at least in Halifax, the setup worked rather well. Even when I hit a WIMAX dead zone, the call would stay connected, and audio would resume when I got a WIMAX signal back. Tower hand offs were not even noticeable in the phone call. I never noticed any latency, but I would have to assume it existed. The audio quality was great, thanks to the G.729a codec. As long as there was a decent WIMAX signal, the VOIP phone call was always of good quality .

Not exactly a straight-forward answer, but while I was attending college I was on the Telus student plan with my Palm Treo 700p (unlimited data.)

I used a third-party software on the treo to turn it into a modem and tethered with my server PC, Voila the house had high(ish) speed connection, and supported both Skype and FPL with acceptable call quality while downloading no less.

So, yes it CAN work, but there are a lot of mitigating factors, including distance from tower and strength of signal at the time you attempt to place the call.
