Re: Patch 0010217

Hi Valerio!

Your dialplan is wrong. You have two choices:

1. Forward incoming call without decoding video. That means
asterisk 
will forward the digital data from one call to the other
call. H324M 
negotiation is end-2-end between the mobile phones. There
are 2 ISDN 
calls, but logically only one H324M session.

[from-pstn]
exten => 1,1,Set(CHANNEL(transfercapability)=VIDEO)
exten =>
1,2,NoOp(transfer=${CHANNEL(transfercapability)})
exten => 1,3,Set(CHANNEL(userinformationlayer1)=38)
exten => 1,4,NoOp(ul1=${CHANNEL(userinformationlayer1)})
exten => 1,5,Dial(Zap/0043123456)

2. Forward call with decoding/encoding video. That means,
that h324m_gw 
will decode the H324M session into Asterisk audio and video
frames. 
Thus, for the outgoing call leg you need h324m_call to
encode the frames 
again. Thus, there are again 2 ISDN call, but this time we
have 
logically 2 H324M session. The first from caller to h324m_gw
and the 
second from h324m_call to the callee. Make sure to set the 
transfercapability  just before the outgoing Dial command.

[from-pstn]
exten => _X.,1,h324m_call($h324m-decoded)

[h324m-decoded]
exten => _X.,1,h324m_call($h324m-decoded-encoded)

[h324m-decoded-encoded]
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/0043123456)

Hope that works. Please report your results.
