Hello,
Has anyone gotten RTP header compression working with LLQ? I have tried
different methods (legacy FRTS and class-based FRTS) and none of them worked.
I could only get it to work if I used MLP and attached the LLQ policy to the
virtual interface. That seemed to work fine. Short of MLP, nothing worked for
me.
Here is the compression section of the show policy-map interface output:
compress: header ip rtp UDP/RTP (compression on, Cisco,
RTP) Sent: 0 total, 0 compressed, 0 bytes
saved, 0 bytes sent rate 0 bps
According to the output, compression is on and it is using Cisco format. In
the MLP case, compression was using IPHC format.
So what are the differences between the 2 formats and why did MLP work and
other FRTS methods didn't work? Anyone has any idea? Thanks.
JD
