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.
Regards,
Ricardo.

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".

Hi,
All SIP ALGs are broken one way or another. PIX is not an exception. It is just impossible to keep up with all types of SIP messages and headers and usages of the phones. It really depends on how you use the phones. It might or might not be a problem for your particular use. My experience is that rtp/mediaproxy is far more reliable than PIX.
Cheers, Richard
