Dear all,
I fixed the issue by myself.
I have edited chan_sip.c file to avoid sdp version gettng increment.
I think this is a bug of asterisk. According to RFCs it should increment it
only it there is change on SDP message body. chan_sip.c alway increase it by
one at every SDP message. I have edited the below part
/* Set RTP Session ID and version */
if (!p->sessionid) {
p->sessionid = getpid();
p->sessionversion = p->sessionid;
} else
p->sessionversion*++*;
As......
/* Set RTP Session ID and version */
if (!p->sessionid) {
p->sessionid = getpid();
p->sessionversion = p->sessionid;
} else
p->sessionversion;
I have removed ++. I am not good programmer. But asterisk lover.
I dont know this is the best solution. However I can receive calls from Acme
packet.
And other important thing to tell is THIS IS NOT A CODEC ISSUE.
thanks everybody
kind Rgds
Daminda
