asterisk users - Jan 2006 - Packeting multiple GSM frames in one IP packet - Help needed.

Hi,

We have a task to reduce voice call bandwidth. IP+UDP+RTP are using 40 bytes per
packet and for voice GSM FR 33 bytes. We are trying to reduce this bandwidth
accommodating multiple GSM frames in one packet. If we want to use per packet
10 GSM frames how to do this using asterisk? Assume the sip client is able to
split these packets in to individual GSM frames.

Any help will be sincerely appreciated.

Thanks & Regards,
Sheshu.

Why don't you just buy some g729 licences?

Is this a trunked IAX connection?
