heres my scenario softphone--------->Asterisk( outgoing call recording )---->Call Provider<br>I am recording all outgoing calls on asterisk so its obvious that there is no native bridging . Suppose if i am using gsm from softphone-->asterisk and then what codec should i prefer for asterisk- > provider ?? Bandwith is not at all a problem between asterisk->provider connection . So if i am using gsm from softphone to asterisk ... then what would be better choice ? sending gsm to provider or ulaw/alaw ? I suppose asterisk already touches audio stream since it is recording to wav file but what i want to know is do asterisk sends same gsm stream ahead to
<br>provider ( and reduces cpu usage ) or it still have to transcode for recording ? because if its transcoding anyway then sending ulaw/alaw stream ahead would be better right ? or am i missing something :-/ <br><br><br>
Also what would be better if i use g729 from softphone-->asterisk( capable of g729 transcoding ) should i send g729 ahead or ulaw/alaw? <br><br>
