That's actually a deep architectural observation with which I can only wholeheartly agree.

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.

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.

I also agree. We have moved all our users to a port other that 5060 to bypass all those broken SIP ALGs. They are truly a support nighmare. We also find that rtpproxy is extremely reliable and we use it extensively.
