[asterisk-users] Bridging Video Calls using Zap
Hi!
For demonstration purposes I try to bridge an incoming video call from a
3G mobile handset to another 3G mobile handset using asterisk as switch.
On the incoming call leg I see all expected bearer capabilities
(Digital, 64k Transparent, G.7xx 384k video) but on the outgoing call
leg the bearer capability G.7xx 384k video get lost and therefore the
call is dropped from the mobile operator.
What I have tried so far ist to use SetTransferCapability(VIDEO) but
this does not change the behavior.
Is there a way to set or preserve the bearer capability for the outgoing
call leg?
cheerio
Steve

Hi,
You have to modify the setup sent for the call outgoing...
