Cisco phones use udp ports 16384-32776, while Xlite uses something like
udp ports 8000-8050, and Polycom phones use another range, etc. If you
worked for a large company that didn't have any sip phone standards and
you had to open everything that _could_ be used for rtp, then you really

Remember that SIP and RTP are different - SIP is used to set up the

RTP uses multiple ports, typically in the range 1-2
