Has anyone had problems with RTP Header Compression. A customer is running Voice over IP over our MPLS VPN. They are experiencing packet loss and the interfaces are incrementing flushes and output drops. I have run SAA and seen some SAA packets dropped also. The circuits tested clean so I am beginning to suspected RTP Header Compression. It is enabled on all interfaces and it causes the router to process switch so I am thinking this is creating delays and leads to the flushes and the drops.
Am I on the right path?
Has anyone else seen a problem with RTP Header Compression?
