[Asterisk-video] h324m outbound call - no user information layer 1 in bearer

[Dawid]

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(${EXTEN}@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(${EXTEN}@video)

[video]
exten => _X.,1,Dial(SIP/${EXTEN})
