I got problem with outbound video calls. There is no 'user information
layer 1' centent in Bearer Capability header, but i know that should be
something like this: 'User information layer 1: H.223/H.245 Multimedia
(38)'.
The LLC header is unnecessary becouse my GSM operator supports only
Bearer. Incoming 3g calls working great.
I've got Asterisk 1.4.22 with llc path, llc patched libpri and Sangoma
A104d QUAD T1/E1 AFT card.
My extensions.conf:
[from-local]
exten => _X.,1,h324m_call(${ext...@3gout)
[3Gout]
exten => _X.,1,Set(CHANNEL(transfercapability)=VIDEO)
exten => _X.,2,NoOp(transfer=${CHANNEL(transfercapability)})
exten => _X.,3,Set(CHANNEL(userinformationlayer1)=38)
exten => _X.,4,NoOp(ul1=${CHANNEL(userinformationlayer1)})
exten => _X.,5,Dial(Zap/g0/${EXTEN})
[from-pstn]
exten => _X.,1,h324m_gw(${ext...@video)
[video]
exten => _X.,1,Dial(SIP/${EXTEN})
