[Asterisk-Users] Asterisk Codecs [G.729]

[Alex Volkov]

Have a look at the following document. I know it is not *exactly* what you are asking, but it gives you an idea on how the actual bandwidth consumption changes depending on the actual network medium you are utilizing.

Have fun.

  Hello all,

  I'm looking for advice for codec that works best for asterisk.  Anyone has real testing with all codecs, specially with G.729.  I have tested with single call on few codecs that come with asterisk by using IPTraf and the rate as of below:

  ulaw 64 Kbps, sample-based Also known as alaw/ulaw 166kbits/sec
  alaw 64 Kbps, sample-based Also known as alaw/ulaw 167kbits/sec
  gsm 13 Kbps (full rate), 20ms frame size   66kbits/sec
  speex 2.15 to 44.2 Kbps     n/a
  iLBC 15Kbps,20ms frame size: 13.3 Kbps, 30ms frame size 57.6kbits/sec
  G.729 8 Kbps, 10ms frame size    license

  Have anyone test it with G.729?  Please let me know.

  Thanks.
