Now I am able to receive the call from 3G to SIP and can view the video both ways. But I can't hear AUDIO on either side. Let me know if any settings needs to be changed

I have been out of the loop for some time, but as of a few month ago,
this would not have been possible.

As you know, you need a patched Asterisk to successfully negotiate
video with the IAX2 protocol., due to the inherent limitations of the
protocol.  In addition to that, your SIP endpoint needs to support the
same type of Theora fragmentation as iaxclient does.  I would assume
that your SIP endpoint uses the proposed Theora over RTP draft, which
would make it incompatible with iaxclient.

About a year ago I proposed some enhancements to the IAX protocol to
better support video fragmentation and better codec negotiation.  The
level of interest in the Asterisk community was on the low side and I
assume it will stay low, until somebody actually goes ahead and comes
up with working code to implement these features

Hi,

What you've done to be able to receive the call from 3G to SIP and 3G
caller be able to view the video?

Thanks

Welcome,

At the beginning I would like to thank Sergio for his great work ;-)
Second thing: Could you upgrade your code to support newest SVN
versions of xmprpc-c. The 1.1 version is unable to compile since GCC
4.3 and so we all have to use SVN versions :/

Whatever I do, I get:
