cRTP in MPLS VPN

[unitech]

If customer config cRTP in CE Router (to PE link), do the PE router need to do something or cRTP support only in pure point to point link (layer2)?

Hi,

cRTP should be configured for both sides, CE and PE in order that you can reach to a better voice quality. If it is a F/R VoIP configuration " frame-relay ip rtp header-compression" command line should be under the both sides of CE and PE sub-ifs. If It is leased-line, i mean hdlc encapsulation is on, directly put ip rtp header-compression for both sides. You may find an awful lots of information about cRTP if you give a search on CCO.
