I have recently leapt into VOIP to replace my home Telecom line, (which does not work when it rains). Broadband is fine.

I signed up with 2talk and have got a Linksys SPA-2102 and iPhone running Bria connecting and working well at home.

The iPhone works well on 3G, so I can conclude that my configuration for connecting to 2talk is correct.

At work, I thought it would be cool to be able to use the home phone there too, (I look after IT), we have a MS ISA server.

The iPhone will not connect to 2talk at work. I assume that the ISA server is preventing the conneciton to 2talk. I have opened ports 5060 TCP and UDP, 50600 TCP and UDP, 5004 UDP, 10000 UDP 16348-32768 UDP and 3478 TCP and UDP on the advice of 2talk. Still no joy.

Has anyone had any success in getting Bria on the iPhone connecting to 2talk from behind the ISA Proxy?

Thanks in advance.

Does it register with no audio or fail to register at all?

If you get registration and no audio you're not opening the correct ports for RTP audio.
I don't know what ports 2talk use but you can get an idea looking at the SPA2102 status page during a call.

It does not register at all. Good advice. I will check out the SPA-2102 tonight.

Cheers

How do you deal with the multiple phones registering to the one sip. I have the same setup but have found that the last device to register gets the incoming calls. So if i register the voip software on my android that is where it will ring and not my phone at home. I want it to ring in both places. Any ideas?

I am not quite an expert in this and I can't quite be sure, but I am fairly certain that each phone rings on an incoming call.

In the 2talk setup under the Locate Me/One Number section you can enter the numbers eg, 2819500, 2819500-1, 2819500-2 for each phone and while you are doing this in the "Ring this Number" drop down, select the "At all times" option.

i'm pretty sure that this will do it.

You can't do this with SIP. The last registration will always receive the incoming calls.

2talk allow you to have mutliple extensions by allocating them a suffix and then using a ring group to ring them all at once.

That is what I thought. Slight lapse in memory, im actually with Italk. I will check the website out and see if they do extensions.

Have you tried using the native 2talk app (free) from the app store? It is an old app with poor codecs and doesn't support multitasking, but should have all the 2talk settings correct.
Looking at mine it lists:

Rtp/media port: 51988
Sip port: 50600

Microsoft ISA Server has been superceeded by Microsoft Forefront Threat Management Gateway 2010 (TMG 2010). You will need this new version (which is free is you have software assurance) to support SIP connections I believe.

Thanks Paulspain. That would explain it then.
