Odd CLID

[Joe Price]

Hello All -

I have a CUCM Cluster with 1 Pub and 2 Subs running 10.5.  The system has a PRI for outside calls.  I have a user that keeps getting calls with CLID of "unavilable@10.10.10.10" (where 10.10.10.10 is the ip address of the one subscriber.)  The calls originate from the outside of the PRI.  Anyone experience this before?  Anyway to block these calls?

You have a SIP trunk b/w your CUCM and GW ? You won't be able to use a TP etc to match a non-numeric string such as a unavailable. Your best option use a SIP Profile on the GW and change the unavailable to a random dummy ANI. Then you can block all calls on CUCM coming in with that dummy ANI.
You might need to manipulate multiple SIP headers depending upon what is being relayed by the GW.

I still have doubts about the IP after @. If the calls originate outside of the system, the IP should be of the GW since it would be sending the call to the your UCM.

No SIP just PRI.  That is why this is so confusing.

Can't be. You cannot terminate a TDM connection directly to CUCM. You need a GW in between. Is this a business edition ?
