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

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.
