Hi All,
This is my first mail to the list. I have a requirement of playing audio
messages to the called party. I am using following configuration in
"extensions.conf" file.
exten => 789,2,Dial(SIP/456,20,A(/tmp/soundfile))
Here I am calling from "SIP/123" to the extension "SIP/789". In the dialplan
for extension "SIP/789" the destination number "SIP/456" is dialled and the
announcement recorded in the "soundfile" is played to the user listening at
"SIP/456" when the user answers the call. But there are two issues faced by me.
1) The voice quality of the announced message is very poor. The issue does not
seem to be related to the "soundfile" because if I use the same recorded
"soundfile" to playback to the calling party(SIP/123 in this case), I get a
good voice quality. Also if I use the following configuration:
exten => 789,2,Dial(SIP/123,20,A(/tmp/soundfile))
i.e. I callback the calling number(SIP/123) and play the announcement, even
then the voice quality seems good. But if a number different than the caller is
dialled and the anouncement is played, the sound quality deteriorates a lot.
Could someone please explain why this behaviour.
2) Is there any other mechanism(Other than the one shown above) of palying a
message to the called party.
Any help on the above two issues shall be appreciated. Hope to receive a reply
soon....
Thanks and Regards,
Lucky
