CUCM Inbound Call Configuration?

[Signups]

Hi, Ive been working on a lab setup for CCNA. I have a 2901 with the UC license applied and a SIP provider.

I have outbound calls working on the phones in the lab and im now trying to get inbound dialing working.

I have a DID setup at the SIP provider which is set to route calls via sip registration. I have debug ccsip all enabled on the router and when i place an incoming call from another system i can see via the debug logs that there are inbound sip packets first to the router and then to the CUCM which is where the trouble seems to be.

There is only one sip trunk configured in CUCM. I think the problem is that i have not told CUCM where to send the incoming calls to. Can anyone tell me how to do this ? I have a hunt pilot number i would like to send all incoming calls to

1) It seems that CUCM SIP Service is not identifying you gateway IP If you have the SIP Trunk Configured to Gateway from CUCM make sure to bind the SIP traffic to proper IP Address on Voice gateway.

Yes! after adding 
voice-class sip bind control source-interface BVI10
voice-class sip bind media source-interface BVI10

to my inbound dial peer the error has disappeared.

The only thing im missing is how do I get CUCM to route all inbound calls from this dial peer to a directory number ? Normally with CME I would just do an earphone bit its not an option here.

You can create a translation pattern and route call to a DN .

Say you want to send the call to 2001 and you are receiving a call on 5XXX number then just create translation pattern 5XXX and convert it to 2001 assign proper CSS and it should work.

I thought that would resolve the problem however when I dial the DID from another phone system I get the following 

Here is the revelent part of my config 

voice translation-rule 3
rule 1 /^.*/ /666/
!
!
voice translation-profile External_To_Hunt
translate called 3

Most probably you have not applied proper CSS on the SIP Trunk in CUCM. Go to SIP Trunk look for Calling Search Space and apply appropriate.

hi.....

I don't have SDI recording file

I did all procedures for call recording but not working ......i have CUCM 9.1 

[kgibs42]

The External Phone Number Mask MUST match the extension’s FULL 10 digit DID or calls made externally to the device will not go through. Even when all other functions of the phone work like internal inbound/outbound, internal outbound to external, etc.

[Roger Kallberg]

The External Phone Number Mask (EPNM) do not have any correlation with any inbound calls, neither external nor internal. It is only used for outbound calls, if the applicable configuration is in place.
