Hi guys, i am configuring a  video call between two grandstream video phones (GXV-3000) which i don't recommend for being a crappy set of devices.

I am using the latest freeswitch FreeSWITCH version 1.2.0rc2+git~20120618T111915Z~11a745cf76+unclean~20120618T121534Z .

But no video call between those devices.

However video call between a Grandstream and an Android Bria Phone works ( i don't recomment bria too, but it helps me with some tests).

Here is the log of two grandstream that fails:

http://pastebin.com/tXZ4DhKM

it keeps stuck on the line that says:

2012-06-18 11:58:35.144424 [DEBUG] sofia.c:5838 Channel sofia/internal/215 entering state [calling][0]

and then continues.

And here is the log of a grandstream and a bria that works:

The call is started from the Bria, starting the call from Grandstream will not work.

If i configure the Grandstream to not send video they can place calls and it will work for audio, if i configure them to start video automatically they will not work, in fact they can't place any call but they can receive calls from other phones.

But if i put:

    <param name="inbound-bypass-media" value="true"/>

at the sip profile they are attached to they will work, however i don't like this solution, cause i want to deploy them behind a firewall at different places.

Tried before:

    <param name="inbound-proxy-media" value="true"/>

but it didn't work, the only way to have this working is setting inbound_bypass_media.

Any help on this issue ?

Thanks.
