[Asterisk-video] Generate outbound 3g call will .call file and local channel

[Konstantinos Liadakis]

My best guess regarding outbound video dialling with .call files using a 
localchannel is the following

Call file
Channel: Local/XXXXXXXXXX at from-dialer1/n
CallerId: 1506
Context: from-dialer1
Extension: XXXXXXXXXX
Priority: 1
Set: CHANNEL(transfercapability)=VIDEO
Set: CHANNEL(userinformationlayer1)=38

[from-dialer1]
exten => _X.,1,Set(CHANNEL(transfercapability)=VIDEO)
exten => _X.,n,Set(CHANNEL(userinformationlayer1)=38)
exten => _X.,n,Dial(Zap/g0/${EXTEN},30)
exten => _X.,n,h324m_gw(play at video-campaign1)
exten => _X.,n,Hangup()


[video-campaign1]

exten => play,1,h324m_gw_answer()
exten => 
play,n,mp4play(/var/lib/asterisk/sounds/autodialer/user_recordings/video/26/gauloises1.3gp)
exten => play,n,Hangup()

But yet, it does not work. When execution reaches h324m_gw_answer call 
hangs up.

Below is the cli
