Troubleshoot / debug dial-peer and call routing on CME / UC-540

[rochdalemis]

Hello,

What debug commands I can use to see which dial peers match a phone number dialed and which dial peer is actually used to route a call?  I also want to see which port the call is routed through.

I plan to use csim start command from CLI to test routing.

Thanks for your help in advance!

I usually use the debug voip ccapi inout to debug any routing issues, it will give you the whole bulk of info for the call.

Javalenc, I have tried to use debug voice ccapi all and while it was providing info on called number and chosen dial peer, the call, actually, was going through another dial peer. So, perhaps, I was looking at a different level.

I have an overlapping dial-peers (FXO and SIP), and while debug shows that a peer associated with an FXO port is used, the call actually goes through SIP trunk.

Any thoughts?

Thanks in advance,

Greg

That would totally depend on your dial-peer configuration, preference and hunting mechanism

You'd need to post your config for anyone to help.

Ok, but is there a way to see what decisions IOS makes as it goes through a list of configured dial peers, preferences, hunting groups?

I already posted a question here, but received back only what I already knew.

Briefly, below is what I have. When a number such as 3550000 is dialed, the call always goes through SIP trunk. changing pattern to 35..$ removes the dial peer from match report (debug voice dialpeer all), but the end result does not change.

Having an ability to see IOS decision making process would help to understand why things don't work.

"Debug voip ccapi inout"  will tell you which Dial-peers are being matched.  If you search in the text for "outgoing

dial-peer" you will see which dial-peer it is matching.

Looking at your FXO setup, you might have an easier time setting up a Trunk Group for all FXO lines to be in.  This way, you don't have to create 8 differenct dial-peers for one dial-string.
