CUCM blocks anonymous calls

[allahverdiyev]

Hello,

I have implemented incoming call block filterin based on ANI in cucm. But unexpetedly it also block anonymous calls, although I have added "blank" translation patterns. I could not find pattern to match anonymous calls, as I guess it is reaching as "<sip:Anonymous@" from sip gateway. I don't have access to gateway so all should be done on gateway.

I did ^[0-9].! in TP, but did not work. 

I also find a way to apply sip normalization script. But I want to left it as last option.

Is it possible to match letters(for ex. starting with "a" to match the word of "anonymous") in translation pattern?

Any other solutions please asap?

regards

Did the anonymous call get through before the block?

Here is my setup for reference.

This does not allow anonymous calls.

Of course, it went through before :)

So the way I see it is you have two options.
-Change the "anonymous" to something different with a SIP normalization script
-Move the call blocking to the routers

I have gone through sip normalization, thanks
