Help blocking specific inbound caller ID

[jtanner02]

I trying to block a specific number that continually calls in and harrasses one of my buildings. The process for doing that... well, I'm struggling. I'm definitley NOT a CUCM guy, though I'm trying to learn.

Anyway, I make a Partition for calls to go through and another for calls to be filtered. I make a CSS to match them. 

The directions tell me to make a Translation pattern of "!", but it tells me that Translation Patterns cannot begin with that.

I could really use help CUCM 11

Hi,

Whats the call flow?

The calls are coming from the PSTN?

This has been asked and answered on many occasions in the forum. If you use the search functionality in here I’m sure you’ll find what you need to set this up.

For example this one.

Thanks. I do know about searching and found & followed this very same walkthrough. As stated in the OP, on step 5 when it comes to creating the translation pattern I get an error saying the the TP can't begin with a !

We have this setup and we have translation that has the match set as !

Could you please share screenshots of your configuration?
