I set the config to use the GSM codec. According to various web sites, GSM should be 13 Kbps, but I'm measuring around 35 Kbps. I understand that this difference is caused by overhead from bytes added due to the RTP, UDP and IP packets. I also see that each RTP packet contains 33 bytes of GSM data while the entire packet is 87 bytes. That's over 160% overhead. How can I change the frame size to include more GSM data bytes in each RTP packet? I would like to increase the size of each packet to around 165 (5 times the current size). This would decrease the overhead to about 32%. I realize this will also increase the latency 5 times as well. So how can I change the bytes per frame for the GSM codec? Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/attachments/20100315/c50eb0eb/attachment.html>
