Can anyone interpret the above parameters. I am just a novice with IP Telephony. How will the gateway process the parameters? How to know if its inbound or outbound? Is it from top to bottom process, meaning from first dial-peer to the end? thanks

200 voip sends everything from 7XXX to 10.12.0.2 first then to 10.12.0.3. This is done using the preference command under dial-peers having the same destination pattern. preference order is from highest, 1-10. It also marks the H323 signaling traffic to CS3. I would need to see more config t break down any further.

Dial-peer 310 pots is like a frankenstein peer. I would need to see more config before I would tell you, however it might launch server session )looks under application config for this service file when any number starting with a 21 is dialed. Feel free to paste more config...

Thanks!

what "destination-pattern 21T" means. How will I know that a particular dial-peer is an inbound or outbound process?

When you're assigned voip duties you need to study the cisco documentation, there is no way around that.

its for outtbound which means you Dial no start with 21 after that any digits.

might be a good idea if you read the CVOICE and GW&GK material because as Paolo mentioned, the only way to learn is to study, and most of all self-study.

after you read all the provided material you will understand what those dial-peers do
