[Freeswitch-users] Bridging dingaling to sofia

Wed Mar 21 08:36:21 PDT 2007

A *complete* console trace of the call that doesnt work would make it easier to debug. including the ip (the XXX actually hides an important piece of info as to if the ip is internal or public so at least provide XXLOCAL XXPUBLIC).

The easiest way to do this is to execute

/usr/local/freeswitch/bin/freeswitch | tee /tmp/console.log

then reproduce the problem, stop freeswitch and post console.log.

Subject: [Freeswitch-users] Bridging dingaling to sofia

Hey all,

I've been playing around with trying to bridge dingaling to sofia for some time now.  I've had some success.

1) I can call to googletalk using a local sip registration
2) I can call to googletalk using a remote sip registration

3) I can call from googletalk to a local sip registration
4) I can call from a local sip registration to a remote sip registration

In case my terminology is bad when I say local registration I mean that the soft-phone is registered with freeswitch.  When I say remote sip registration I mean that the soft-phone is registered with my standard SIP provider.

The problem is if I call from googletalk and attempt to bridge the call to my remote sip provider the call rings, but there is no audio.

I've tracked through the console and here is the piece that's different.  This piece never shows up if I attempt to bridge the call to a remote sip registration.  I copied this from the console when bridging to a local sip registration.

The weird thing is that if I call the same extension in default_context.xml using a sip phone registered locally it bridges without any problem to the remote sip registration.

Can anyone please help with this?  I've been battling it for a long time now.  I've learned a lot which is good though :-).

By the way I just downloaded the last svn version today, so I couldn't be on a more recent version :-)  Also if this isn't the best place to address this type of question if anyone could point me in the right direction that would be greatly appreciated.

Thanks for any help.

Kieran.
