[Serusers] Is RTPproxy needed even when there is a Cisco PIX?

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.
