<br>
I finally managed to make it. Jack was right, we needed to use h324m_call<br>
<br>
This is how i did it<br>
<br>
callfile<br>
<br>
Channel: Local/XXXXXXXXXX@from-dialer1/<u></u>n<br>
CallerId: 2111811499<div class="im"><br>
Context: video-campaign1<br>
Extension: play<br>
Priority: 1<br>
Set: CHANNEL(transfercapability)=<u></u>VIDEO<br>
Set: CHANNEL(userinformationlayer1)<u></u>=38<br></div>
Set: phonenumber=XXXXXXXXXX<br>
<br>
[from-dialer1]<br>
exten => _X.,1,Set(__phonenumber=${<u></u>phonenumber})<br>
exten => _X.,n,h324m_call(play@from-<u></u>dialer1)<br>
exten => play,1,Set(CHANNEL(<u></u>transfercapability)=VIDEO)<br>
exten => play,n,Set(CHANNEL(<u></u>userinformationlayer1)=38)<br>
exten => play,n,Dial(Zap/g0/${<u></u>phonenumber},30)<br>
exten => play,n,Hangup()<br>
<br>
[video-campaign1]<br>
exten => play,1,Wait(1)<br>
exten => play,n,mp4play(/var/lib/<u></u>asterisk/sounds/autodialer/<u></u>user_recordings/video/26/NEW_<u></u>Mercedes_SLK_2012.3gp)<br>
exten => play,n,Hangup()<br>
<br>
<br>
Regarding Mituls suggestions, below is the .3gp file mp4info<br>
<br>
3gvideo:~# mp4info /var/lib/asterisk/sounds/<u></u>autodialer/user_recordings/<u></u>video/26/gauloises1.3gp<br>
mp4info version 1.6.1<br>
/var/lib/asterisk/sounds/<u></u>autodialer/user_recordings/<u></u>video/26/gauloises1.3gp:<br>
Track Type Info<br>
1 video H.263, 19.750 secs, 55 kbps, 176x144 @ 8.000000 fps<br>
2 audio AMR, 19.620 secs, 13 kbps, 8000 Hz<br>
3 hint Payload H263-2000 for track 1<br>
4 hint Payload AMR for track 2<br>
Tool: mp4creator 1.6.1<br>
<br>
What is the difference between h324m=bc and h324m=llc?. I had llc and changed it to bc. Now i think that video is smoother. Is it just my idea, or could it be true?<br>
<br>
Now that dial command is in the dialplan, ${HANGUPCAUSE} gets populated, and one can have better idea why a call failed. Now if a call fails one can distinguish if device is switched off or device is not capable to receive video call (as long as voicemail is disabled).<br>
<br>
The problem that remains now is when phonenumber has voicemail enabled and device is not video capable. I am still not able to understand that the call has failed. Hangup cause and dialstatus indicate that call proceeds ok, but call goes into voicemail.<br>
<br>
Nobody has ever come to this problem?<br>
<br>
Thank you very much Mitul and Jack for helping me implement this way of autodialeing for 3g video. Wish there was a way to handle better failed calls.<br>
<br>
Your experiences are welcome<br>
<br>
Best regards<br>
