Calls to Mobile Phone not working

[Abhishek Singh]

Have an issue with calls being routed to a particular cell phone number .

Checked the dial - out code for a US location -- 9-1-XXXXXXXXXX  and 1-XXXXXXXXXX -- both used . Checked the RPattern configuration and it seem to have a specific x[2-9]xxxxxxxx which seem to work for that specific location to route calls -- but for this particular mobile phone.

Have to check the CCM traces between the ip phone and the mobile phone -- but would appreciate if someone can suggest -- what else can I can check -- as the calls is not even reaching out to the cell number.

CCM version : 7.1

What trunk is the call going out on, SIP, PRI, FXO? We will need to see a debug of the call, also how is the gateway controlled in CUCM, is it SIP, H323, MGCP?

H.323

PRI Link

Waiting for the debugs .

==================

DNA output --- shows the call being routed succesfully through the H.323 gateway -- can somone also guide on what are the critical things in the DNA which can point out to a specific issue/ which we can check -- apart from the tool itself providing information on how the call gets routed IN/Out of the network.

After checking the following debugs:::

debug isdn q931

debug voip ccapi inout

debug voip dialpeer

We seemed to have struck gold

What we found in the above mentioned logs was that a 10 digit RPattern was configured for this specific location -- which had the same area code as the DID -- and on the other hand the dial peers have a 11 (1-xxx-xxx-xxxx) digit forwarding configured on the gateway.

Also to point to an instance -- the calling party / 10 digit pattern -- was being shown in some of the call legs as " called number "  -- a re-routing scenario  -- also pointing to a RPattern -- dial peer configuration flaw.

Hope I made sense

I once had a similar problem. There the external mobile phone number was accidently configured as a directory number in CUCM. The symptom was the same.
