Hey Paul,
Thanks for the reply Paul. The protocols SCCP and MGCP are pretty well known protocols in Cisco VoIP. For example, SCCP is used for Cisco IP phones to register with the Cisco Unified Communications Manager (CallManager) and analyzing the transactions between the two can help determine issues with registration. MGCP is also a call-processing protocol. EIGRP as you may know is a Routing protocol. Unfortunately I cannot find RFCs or detailed specifications for SCCP, but there are for EIGRP and MGCP. Here is all the info I can gather on them:
SCCP = Skinny Call Control Protocol (Usually just referred to as Skinny)
Runs over TCP, on port 2000
Note: This shouldn't be confused with the Signalling Connection Control Part from SS7 Signalling Stack
http://en.wikipedia.org/wiki/Skinny_Call_Control_Protocol
http://wiki.wireshark.org/SKINNY
EIGRP = Enhanced Interior Gateway Routing Protocol
RFC = http://tools.ietf.org/html/draft-savage-eigrp-00
MGCP = Media Gateway Control Protocol
RFC = http://www.ietf.org/rfc/rfc2705.txt
By the way, thanks for letting me know that Message Analyzer was the new NetMon. I installed it already, although it does look a bit more confusing than Network Monitor. For example, it's not clear how to choose which Network Interface I want to monitor because the names are not the same as the connection names. Also when I open up a previous capture, I cannot separate the traffic based on which application it was using. I hope these will be addressed in the final release.
Thanks!
John
