QoS + Compress RTP

[rbarroso]

Hi, we have a Frame-relay wan link betwen two cisco 3745 with 12.2(15)T9 in both routers.

Also implement QoS as show below:

policy-map Policy512Kbps-FR

description Politica de QoS Frame-Relay

class RTimeVC

bandwidth 160

class RTimeVoIP

priority 100

compress header ip rtp

class Bussiness

bandwidth 158

random-detect dscp-based

class Less_Best_Effort

bandwidth 23

random-detect dscp-based

class Best_Effort

bandwidth 45

random-detect dscp-based

But sometimes, the Compress don't work.

Any Idea? Any Bug undocumented ?

Duplicate post!

So what command have you given to enable RTP header compression ? At the DLCI level or at the sub interface level ?

Can you paste a sh ip rtp header-compression detail

12.2.15T9 is a little too old, do you have the same IOS on either sides of the link ?

The compress are at Class Level.

class RTimeVoIP

priority 100

compress header ip rtp

The IOS version are equal in either sides of the link

If i do "sh policy interface Serial0/0" a see compress in one way.
