X-RTP Statistics


Several vendors use a proprietary header in SIP to give statistics on the RTP stream. This proprietary SIP header has following names :

 ●  X-RTP-Statistics

 ●  X-RTP-Stats

 ●  X-Siemens-RTP-stats-list

 ●  P-RTP-Stat

When supported then this header can be found in a SIP BYE or 200 OK on a SIP BYE.

The VoIPAnalyzer Tool supports the X-Siemens-RTP-stats-list header.

An example of such a header is :

X-Siemens-RTP-stats-list: MT=0;PS=662;OS=105920;PR=661;OR=105760;PL=0;JI=0;LA=1;SS=0;EN=8;DE=8;IE=00;TCLW=52
