QoS configs VOIP

[bryantsteve]

I have IP phones on a satellite network and would like to try cRTP header compression however the network topology is a C2811 router FE interface connecting to the satellite modem.

As far as I can tell RTP header compression is only available on slower speed serial links.

Is there an option for a FE Interface?

I'm not sure on the 2800 series, but on the 3745 you can run:

int fa0/0

ip rtp header-compression

HTH,

c28(config-if)#ip rtp ?

priority Assign a priority queue for RTP streams

reserve Assign a reserved queue for RTP streams
