Hi,
I'm deploying a VoIP server using SER and I would like to know if I need to install RTPproxy (or Mediaproxy), because the network where the server will be placed already has a Cisco PIX 515E which has this feature that analyses headers of SIP messages and I suppose that rewrites them to avoid NAT problems.
The Cisco PIx helps you in rewriting SIP messages if your SIP proxy is behind NAT - that means if your Cisco-PIX network uses NAT, the Cisco PIX provide means to solve this NAT issue.
But I do not know if it is capable of "far end NAT traversal".
