How to troubleshoot incoming calls not working on call manager 7

[Taylor Scott]

How to check why incoming calls are not working in call manager 7 office phones?

Start by debugging the GW, then depending on the debugs, you can get a hint of what might be wrong in CUCM so you can adjust.

[Brandon Pierce]

Well, you can start by using the Dialed Number Analyzer within CUCM on the servicability page.  Next would be RTMT.  You would also want to check the gateway if it got to that point....but this all depends on protocol(s) used.  Are you familiar at all with a UC environment? 

EDIT::: Missed the big keyword INCOMING not outgoing....my bad.  Ignore the above.  Go with Jaime's advice, start at the GW since that is the first point inbound.

[Brandon Pierce]

Go with Jaime's suggestion, I missed the keyword "INCOMING" somehow.... busy morning.

Just to add Jaimie and Brandon's list:

1. What type of GW you have?

2. Are you sure that there is no issue from Telco?

3. Are the outgoing calls working?

4, Calls to the Ext. working?
