Thanks Anthony,
I should have looked in the SRND - I was googling around for port
utilization. Your explanation sounds plausible, it is a SCCP phone and I've
never seen any other port numbers pop up like that.
In this case the ACL is actually just running on a 4500X, no real firewall
in play to

Is this a SCCP or SIP phone? I wouldn't worry too much about where you saw
"IPVMS", it's likely specific to the context of the chapter/section. I.g.,
Table 6 in Port Usage Guide is only for Phone to CUCM communication

*SCCP endpoints use a non-configurable

I've notice this a few times bouncing on ACL, thought it was worth asking
about.
I see in numerous documentation that CUCM uses 16384 - 32767 for RTP - the
documents specifically say IP Phone to IPVMS.
I observed an 8945 Cisco phone listening on 32768 and 32769 (assuming RTP
and associated RTCP)
