selective rtp header compression

[atou]

I want to implement RTP header compression but just for some ranges. I tried with Parent and child policy-maps but doesn't work.

In attachment you can find the config. I guess I can use the same config for the other side when I change the access-list or not?

Kind regards,

It looks like this will work. I set it up in my lab, why do you think it's not working?

When I add the rtp header compression command, I can't use the Voice_Compression policy-map.

When I remove the rtp header compression command I can use the Voice_Compression policy-map in the Voice policy-map.

Do you know of a solution to my problem to only do rtp header compression for a specific rangez of IP's?
