[asterisk-users] Outbound video Calls

Thu Jun 26 06:18:40 CDT 2008

You could try to use libpri-1.4.7.1-llc-transmit-receive-patch.txt from 
http://bugs.digium.com/view.php?id=11595 to signal H324M in LLC IE too. 
Maybe the switch wants to have it in Bearer Capability and LCC (I once 
had such a switch).

Another reason could be that the telco blocks video calls.

regards
klaus

PS: use the asterisk-video mailing lists
