Block call by CID

[wfranklin]

Heys guys,

I'm a newbie by 3CX PBX Systems but I'm just helping a customer here.

Let's go.

Is it possible block a call by CID? I mean by the source number? Let me explain more, I'm giving a 0800 number (I'm the ISP) to this customer but he does't want get calls from mobile numbers, so I wanna block this call on 3CX system.

How can I do this?

Thanks!

Adding.

I know that can be something under ADD DID/DDI NUMBER.

Thx

Do you mean inbound calls?

If so add 07* to the Number Blacklist in Settings (V14)

Hey Alex,

I'm sorry I forgor to say that it's a Inbound call..

Yes, but if I put it there I'll block all calls right? I'd like to block just to specific DID.

For example.

DID 0800 569 5641 - i'ts just a Toll Free number you know...
Souce to DID is a Mobile Number: +55 11 9 98745698

I need to block just the calls with +55119* to 0800 DID

Got it?

Use the Extension # -> Forwarding Rules -> Exceptions if the DID is associated with just a single extension.
But I am not sure about this if the DID goes to a ring group/queue/etc.

This sounds good to me but I was wondering if that calls go to Group? It will not work beucause there we don't have this option, is int'?

How about Inbound Rules > Inbound Rule Type > C ID number? What do u think? How can I accomplish it?

Thx a lot.

Unless things have changed recently, you can "deal" with CID at the extension level, or a blanket "rule' that affects everyone. If you choose to block a number for the PBX, I don't believe that you can block by prefix, left to right. If the call is routed to a ring group, or non-extension "initial" destination, you could route the call through a "dummy" extension and parse the CID at that point, although, again, I'm not certain that it is designed to deal only with a numbers prefix ( make use of wildcards).

You could probably get this done by adjusting the order of the Inbound Rules.
Maybe you could do something around the lines of e.g.:

- DID A -> Ext A
- DID B -> Ext B
- .......
- DID X -> Ext X
- CID +55119* -> block calls
- DID 0800 -> Queue

This way on every inbound call it would first go through all the other rules and if it reaches the end, right before hitting the 0800 DID rule have a CID rule that would block calls from mobiles. Haven't tried it but I think it should work.
