NAT / Spoof / Hide / Replace CLIP or Caller ID of an extension number for internal call

[Jérôme Wentzel]

Hello World !

Basically I am trying to find a way to do an "Outbound Caller ID" for internal calls.
I am not able to find a solution to replace the CLIP of an extension number for internal calls.

Context:
I have a group of agents servicing one call queue.
I need to find a way to make sure that when an agent makes an internal call, the callee sees the call queue number and not the agent extension information.

This to make sure that agent's call number is not disclosed internally.
Agent's extension are already hidden from the 3CX phonebook.

Is this possible with 3CX ?
The only way I see now is to make an instance of 3CX only for that call queue, but this would create many other problems so I prefer to avoid that as much as possible.

Many thanks in advance

Hi!

I'm afraid that isn't possible with 1 system. In 3CX internal calls made from one extension to another always show the Callers Extension Number. Altering your Caller ID is only possible when making calls to External numbers through SIP Trunks.

Your suggestion might allow you to achieve this, but as you already know from the sounds of it, there are quite a few challenges to connecting 2 3CX systems between themselves using SIP Trunks (because in your case Bridges might not help...), plus it really isn't a 3CX-supported scenario.

What you could try is talking to your SIP Trunk provider to see if they can allow "inter-provider calls" between numbers you own under your account free. This way you would still need 2 3CX Systems, but your could configure one SIP Trunk on each from the same provider and actually make calls between them using the External Numbers.

Hello Nick !

OK, I was afraid that I was reaching a limitation in the use case 3CX supports.
Even with 2 3CX systems people will loose the presence and many other features.

It would be cool to add that as an feature in the future
I will see how people react to this limitation and see how it goes.

Would I need to find a magic solution, I will share that here

Many thanks for your quick feedback.
Amicalement !
