NEED HELP - Use of trunkfreq (or similar) with SIP

Asterisk Asterisk Support
1

Hi all,

I need help regarding to frames length using SIP.

I’m using last Asterisk version and try to call using g729 codec. I’d like to send packages every 40ms (that could be easy with IAX2 and trunkfreq), so how can I force Asterisk to do it using SIP?

Thanks a lot.

To make things clearer… its known that Asterisk sets packetization to 20ms for SIP. My question is about finding a way to change that using g.729 and SIP.
