Hi All,
I have 1 basic query regarding ofer-answer model
Phone1 is sending the offer with 2 audio mlines and 2 video mline like
as follows.
m=audio 3342 RTP/SAVP 0 8 127
a=crypto:7 AES_CM_128_HMAC_SHA1_80 inline:2222222222
a=rtpmap:0 PCMU/8000
a=rtpmap:8 PCMA/8000
a=rtpmap:127 telephone-event/8000
m=audio 3342 RTP/AVP 0 8 127
a=rtpmap:0 PCMU/8000
a=rtpmap:8 PCMA/8000
a=rtpmap:127 telephone-event/8000
m=video 5544 RTP/SAVP 109
a=crypto:8 AES_CM_128_HMAC_SHA1_80 inline:3333333333
a=rtpmap:109 H264/90000
a=fmtp:109 profile-level-id=42800d
m=video 5544 RTP/AVP 109
a=rtpmap:109 H264/90000
a=fmtp:109 profile-level-id=42800d
and phone 2 is responding with all the 4 m lines as follows
m=audio 4344 RTP/SAVP 0 8 127
a=rtpmap:0 PCMU/8000
a=rtpmap:8 PCMA/8000

m=audio 4344 RTP/AVP 0 8 119
a=sendrecv
a=rtpmap:0 PCMU/8000
a=rtpmap:8 PCMA/8000
a=rtpmap:119 telephone-event/8000
a=fmtp:119 0-15
m=video 7878 RTP/SAVP 109
a=crypto:8 8 AES_CM_128_HMAC_SHA1_80 inline:4444444444
a=rtpmap:109 H264/90000
a=fmtp:109 profile-level-id=42800d
m=video 7878 RTP/AVP 109
