Hi Andrew, thanks for your prompt response. However, I am not sure whether IAX trunking can be of any benefit on 33.6kbps link. It shows significant bandwith reduction on 2 and more simultaneous calls. My question relates to single call over such link. Current measurement say that gsm call consumes approx 32kbps in each direction. So, there is no question that single call is only possibility for such link.
I was able to tweak some old H323 implementations to consume far less bandwith by grouping 2 or more audio frames into single UDP packet (at the cost of additional delay and bigger jitter buffer). My question is related to this matter. Is it possible to force Asterisk to package multiple audio frames in single UDP packet even in case of single IAX call. If that is the case then some overhead can be prevented thus enabling conversations even over such a slow link.
