Hi All,
I had a query regarding a general SIP INVITE scenario.
A ------------------ B
(UAC) (UAS)
Now assume that A sends an INVITE to B mentioning that it supports G711
MuLaw.
v=0
o=user1 53655765 2353687637 IN IP4 10.253.6.209
s=-
c=IN IP4 10.253.6.209
t=0 0
m=audio 6000 RTP/AVP *0*
a=rtpmap:*0* PCMU/8000
Can B while responding in its 200 OK, add a few more things in the 'm' line
as mentioned below?
v=0
o=SHOUT 0 0 IN IP4 10.253.6.249
s=SIP call via SHOUT
c=IN IP4 10.253.6.249
t=0 0
m=audio 17184 RTP/AVP 0 *13 101*
a=rtpmap:0 PCMU/8000
a=rtpmap:*13* CN/8000
a=rtpmap:*101* telephone-event/8000
a=fmtp:*101* 0-15
Is this behavior correct on part of B ?
Regards,
Harneet
