Hi all

I have been using Xnet VFX for a few years now and have been trialling a line on 2talk with a view to moving over to the business service. Service works really well but was wondering how I can make sip uri calls via 2talk. Is this possible? Is this what trunking is about? How do other people have it setup?

Also I have been trying to find a SIP android app that works but having been through most of the apps only one seems to work properly, Sipdroid on my Android 2.3.4. Even sipdroid has the problem of sound coming out of the rear speaker as well so not having much success getting a reliable setup on Android. Rear speaker on seems to be a common problem but means echo for the caller.

Apologies if these seem like obvious questions but my knowledge on SIP is basic but growing.

Cheers
Andy

I think if you have Asterisk set up you could make it work, but not on 2talk natively.

URI dialing I believe is quite insecure tho and generally discouraged unless you enjoy regular chat with overseas scammers.

Thanks for the quick reply. I did try Csipsimple but had trouble with the sound breaking up. Might have been when trying over 3G so will give it another go. What vs android are you on?

I was only interested in the sip uri for doing test calls to check on echo problems due tho the rear speaker. I couldn't see any test line offered by 2talk.co.nz. Do you know of a test number I could use?

Cheers
Andy

Outbound URI calling is nothing to do with your VoIP provider - it's your phone or SIP device making a a SIP connection directly with another SIP device.

Most VoIP providers don't allow inbound SIP URI calls to their proxy due to the security issues of doing so, but you can configure inbound SIP URI calling to your own IP and device. The annoying non speech calls many people with Linksys/Cisco ATA's who have port forwarding enabled have is actually script bots in effect making a URI call to the device.

I'm using it on a Galaxy S3. Works pretty well over 3g as long as the signal is good. Perfect over WiFi.

I have tried Bria as well, but found it was stopping my phone from 'sleeping' therefore draining the battery. Others haven't had that problem and say it works great. YMMV.

Also, Android 2.3 (Gingerbread) and above has a built in SIP stack that you can use without any other software. It's pretty basic, tho.

I use csipsimple with 2talk over wifi and had no problem, my 2.3 Android phone has no sim but makes a great in house wireless phone.

Thanks Guys

I re tried csipsimple but after one call the audio gets screwed up with clicking when I use the dial pad, must be my ROM. Time to replace the phone soon anyway but thanks for the advice.
