[cisco-voip] Ip rtp header-compression

[Carter, Bill]

I believe I read RTP header-compression can not be run on MPLS.  With
RTP HC, each router interface between endpoints must have it enabled.
In the past this could cause CPU problems on routers.  I do not use it.
Bandwidth consumption by G.729 is so minimal it isn't really necessary.

We are evaluating QoS on our network and I have a few questions: 

Does anyone run rtp header-compression on an MPLS network?  

Does anyone run rtp header-compression through a GRE Tunnel? 

Is there value in running rtp header-compression on an ATM WAN?
