Block Foreign Numbers

I tried to block foreign numbers on my Mobydick Appliance. If I set the Source as an Extension number, the call goes through but if I use the CID number of the extension, the call does not.
I thought the Source field should be Extension number and not CID number.
Thank you.

Hello @oogunyinka,

I guess you try to block outbound/outgoing calls?
What do you mean by “Extension number”? In the outbound rules the soruce will always be compared with the ${CALLERID(num)}.
If you have setup a differt callerid(num) than the user extension, this will be taken into account.

Best regards,
