What is the method you are using to test the bandwidth. Can you give us a outline how to do a bit rate measurement on asterisk.

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.
