Am I correct in assuming the iaxy (S101I) does not support comfort noise
generation (CNG)? I can tell a difference between a call placed using a
Grandstream 486 ATA and the iaxy. With the iaxy, when the other party is
silent, the sound level abruptly cuts off to zero. This is fairly
annoying and wouldn't be acceptable at a customers' presence. With the
486, random background noise is still heard, more like a traditional phone.
Does anyone have any suggestions or can recommend an ATA with high sound
quality? So far I have tested the Grandstream 286/486 (unreliable) and
Digium iaxy (S101I). I have not been able to find a reliable ATA that
has high sound quality.
I'm still trying to track down the issue, but it seems I'm having more
jitter problems with the iaxy than the SIP-based Grandstream ATAs.
Incoming audio on the iaxy often gets choppy. Has anyone else
experienced this or have any suggestions? I use the ulaw codec on all
devices and I don't believe the issue is available bandwidth (problem
seems to only occur using iaxy.) I have the following jitterbuffer
settings in iax.conf (Asterisk 1.0.7):
jitterbuffer=yes
dropcount=1
Thank you for your time,
