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

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.
