Block Anonymous - IP Office 2

[vladcbv]

Hy Guys,

Happy new year!

I am using IPO 9.1.8
I want to block all annonymous calls coming to SIP. I am following Avaya's docuemntation and it's not working.
Here is what I tried:

Create Short Code
Code: Set this to an unused Short Code (for example *810)
Feature: Barred

Create ICR -
Line Group ID: Set this to the incoming Line Group ID.
Incoming Number: *
Incoming CLI: Set this to ! (for calls where Caller ID is withheld)
Add the newly created short code as destination.
Alternatively you can add any destination to route the anonymous call to instead of using barred short-code.

Call comes as anonymous but the system dosen't block it..

Any ideas? :-?

Thank you,
Vlad C.

For SIP you might need to put anonymous in Incoming CLI.

You caold also use a oppostie way of programming.
Block all calls except the ones where the CLI starts with a 0

ICR

#### this one blocks all calls
Line ID = 0
DDI = blank
CLI = blank
Destination = *81

#### This one allow alls calls were the CLI has a leading 0 AND a valid DDI number
Line ID = 0
DDI = and valid DDI number
CLI = 0
Destination = any valid destination

etc....

This worked on my SIP trunk

Nice but our best spending customers tend to witheld their number, I would not like to miss a call from them...

I wouldn't block it either as anonymous could be anyone and most are probably calls you wanna answer, so far I've only blocked specific CLIs in rare cases.

But for some reason that's what vladcbv wanted to do.

If this really needs to be done I would at least send them to a message telling them why the call is blocked.

I send calls without caller ID (same way with anonymous in the CLI field) to a special auto attendant before they reach me. That is for my home not business. Businesses get lots of calls without caller ID so you have to deal with it but you can also just send them directly to an auto attendant.

Hy guys,

Well my customer dosen't want people calling with anonymous to his 0800 number.. so i have to block calls only for that topic (he is using IPOCC and has 2 topics. )

Now, I have tried with anonymous and it dosen't work :|

Now, I have tried what intrigrant said adding 0 to Incoming CLI and now it only allows number that start with 0. This is it. I don't know though, if someoone calls from another country if it is blocked or not .. I am in Romania..

Thanks for your help!

Talk to the line provider, its fairly normal for the free-phone number provider to restrict its use by callers who withold their number - so you might not need to make the IP Office do it at all.

Stuck in a never ending cycle of file copying.

Hy, that's a good tip. Thanks.

My solution is just a example of how the technique works.
If you want any call with a CLI to get in then add more ICR tables with cli 1, 2, 3, 4, 5, 6, 7, 8, 9 and +

e.g.:
#### This one allow alls calls were the CLI has a leading 0 AND a valid DDI number
Line ID = 0
DDI = any valid DDI number
CLI = 0
Destination = any valid destination
#### This one allow alls calls were the CLI has a leading 1 AND a valid DDI number
Line ID = 0
DDI = any valid DDI number
CLI = 1
Destination = any valid destination
#### This one allow alls calls were the CLI has a leading + AND a valid DDI number
Line ID = 0
DDI = any valid DDI number
CLI = +
Destination = any valid destination

A lot of work but it will pay off...
