Does my asterisk server need the same codecs as my mobile app?

Right now, both my android and iphone voip app is using the G711 codec. My asterisk server is set up to allow ulaw codec, which i understand is the same as G711.

Now I want to start using the G729 codec on my android and iphone voip app. I've upgraded the the sip library on these apps to support this.

Do I also need to install a G729 codec on my asterisk server in order for my android and iphone voip app to talk to each other?

The short answer is no, you don't need install the G729 codec but need enable it in the sip.conf file for allow the codec pass-thru.

Asterisk G.729 pass-thru

The long one is: It depends on your requirements. Some features will demand decoding/transcoding to work and, in that case, you will need to install G729 codec in Asterisk, like:

  • Direct PSTN termination (not through a sip trunking service);
  • Direct connected extension (not SIP ATA/IAD)
  • Voice conferencing
  • Silence detection
  • ...
