We have a situation where a VoIP connection fails when RTP header compression is turned on over a L3 MPLS link. The same VoIP connection works if put over a clear channel link.
Does MPLS support RTP header compression? Does it have to be configured differently for makeing it work over an MPLS link?
Hritter, Thanks for the response. Need calrification on this. Typically cRTP is done at the CPE end and if this just modifies the voice pay-load, why should it be not supported over an MPLS Link. As far as I understand, the payload is not modified in anyway when transporting an IP packet over MPLS link.
