<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi All,<br><br>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.<br><br><span style="font-weight: bold;">exten => 789,2,Dial(SIP/456,20,A(/tmp/soundfile))</span><br><br>Here I am calling from <span style="font-weight: bold;">"SIP/123"</span> to the extension<span style="font-weight: bold;"> "SIP/789"</span>. In the dialplan for extension "SIP/789" the destination number<span style="font-weight: bold;"> "SIP/456"</span> is dialled and the announcement recorded in the <span style="font-weight: bold;">"soundfile"</span> is played to the user listening at <span style="font-weight: bold;">"SIP/456"</span> when the user answers the call. But there are two issues faced by me.<br><br>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:<br><br><span style="font-weight: bold;">exten => 789,2,Dial(SIP/123,20,A(/tmp/soundfile))</span><br><br>i.e. I callback the calling number(<span style="font-weight: bold;">SIP/123</span>) 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.<br><br>2) Is there any other mechanism(Other than the one shown above) of palying a message to the called party.<br><br>Any help on the above two issues shall be appreciated. Hope to receive a reply soon....<br><br>Thanks and Regards,<br>Lucky<br></td></tr></table><br>
