Hi,
I've a problem with ip rtp header-compression.
I've configured a Frame Relay link from 1811 to 1811, and i've configured the RTP header compression.
The main site is A and I've have only one phone in site B.
The header-compression work fine in some situations: call from phone in site A to phone in site B, or phone from site B to phone in site A.
But header-compression doesn't work fine when i call from phone in site B to CME in site A. It's only works IN ONE WAY. I watch the printout of command show ip rtp header compression, i see that matched packets in one way increases, and matched packets in the other way stay fixes.
This is my configuration of frame relay.
Thanks for help.
