H.323 voice (your voip dial peers) will use TCP 1720 as the signalling
(H.225 portion).
TCP 2000-2002 is the Cisco skinny stuff for the IP phones
I have no idea where 2748 comes from though. TCP 2428 (and UDP 2427) is
used for MGCP controls. You don't have MGCP on the R&S lab.
I wouldn't stress out about it. Not a core topic here. If you are looking
to go for the Voice CCIE, I'd know those ports plus the H.245 ones, SIP and
GK as well. Just a thought. But otherwise, no worries. :)

Subject: Matching Voice Signalling traffic
Hello Group,
I am little unsure on the best way to *match* the Signaling traffic.
In the recent past I have a seen a config where the author has used to match
the destination port greater than TCP 3000 , equal to TCP 2000 & 2748. And
also equal to TCP 1720.
Can some please explain why these ports are necessary to match signaling
traffic. I was impression that signaling only uses TCP 1720 :(
And also like RTP using the *even* ports from 16384 to 32768 , I was
impression that Signaling uses *odd* ports in the same range ??
I appreciate any clarification on the above queries :-)
Thanks in advance
David.
