[SIP]

[复制链接]
Synptom:
SIP phone user-agent info: Yealink SIP VP-T49G 51.80.0.80
Both x500 and SIP phone supports H.264 video.
x500 can not collaborate with SIP phone by H.264 video.

Trouble shooting:
1. Did not parse out the SIP phone's H.264 capability description(without a specified max-mbps and max-fs)
    rtpmap:105 H264/90000
    fmtp:105 profile-level-id=428028
2. SIP sent out three H.264 capatibilities, two BPs plus one HP.
The only difference of the two BPs description was one with a specified packetization-mode, while another otherwise.
According to RFC3984, the packetization-mode could be 0 to 2, inclusive. Default value would be 0, which means single slice.
