Hello Mitul and thank you for your reply,<br>
<br>
I tried your example but did not work for me as i am looking to play
an mp4 file using mp4play on the receiving device. I added mp4 play
command at the end but call hangs up. Could you modify dialplan to
play mp4 file?<br>
<br>
${Dialstatus} does not give much information as to what happened to
the call. <br>
<br>
During my tests i realized that the only way to know in more detail
what happened to the call and especially if 3g call was sent to a 3g
video capable device is ${HANGUPCAUSE}.<br>
<br>
From my test i have found the following:<br>
<br>
If device is switched off (<b>this number has not got voicemail
activated</b>), but device<b> is video capable</b> then you get <b>Hangupcause=20
subscriber absent 480 Temporarily unavailable</b><br>
If device is switched on (<b>this number has not got voicemail
activated</b>), but <b>is not video capable</b> then you get <b>Hangupcause=88
incompatible destination 503 Service unavailable</b><br>
If device is switched on (<b>this number has not got voicemail
activated</b>), but <b>is busy whether device is video capable or
not</b>, then you get <b>Hangupcause=17 user busy 486 Busy here</b>
<br>
<br>
A problem arises when mobile number has got <b>voicemail enabled</b>.
<br>
<br>
If device is<b> not video capable</b>, and <b>voicemail is
activated</b> then:<br>
a. if device is on 3g network, then call jusr fails with <b>Hangupcause=88
incompatible destination 503 Service unavailable</b><br>
<br>
b. if device is not on 3g network, then call is redirected to
voicemail, without any hint about it. Major problem here, because
from the dialplan point of view it seems that video was actually
played at the device although it didnt. Receiver ends up with an
annoying voicemail with a buzzing sound. Also call does not hangup
until voicemail times out<br>
<br>
Has anybody got a better idea of how to handle this?<br>
<br>
Thank you in advance<br>
<br>
Regards<br>
