Caller ID forwarding

[Akita47]

We have a request from a customer to have incoming calls initially going to a call queue, and if not answered then forwarded to an external number.
This is working fine, but they have asked if it's possible to have the original caller's ID forwarded to the external party, rather than their office number.
From what I can see, once an internal call has been sent to a call queue, it's not possible to have the original caller ID passed to the external number - is this correct or does anyone have a clever way to do this?

Hello @Akita47
Please note that achieving this may require some changes to the outbound parameter although these changes are VoIP provider-specific and if your VoIP provider allows you to send any other caller id than the one assigned to you.

With that in mind, it would be best to contact your VoIP provider and ask them if they allow this. If yes, kindly ask them in what SIP field they expect this information from and then make the appropriate changes in the 3CX Phone System.

Because if these changes are not implemented correctly, they may break the functionality of the PBX, and you will not be able to make outgoing calls. That being said, after confirming with your provider where the changes have to be made in the 3CX Phone System, kindly navigate to the Outbound parameters of your SIP Trunk and change its variable to "OriginatorCallerID"

Thanks Dimitris, I have looked at the outbound parameters and we've had it working if the call is forwarded directly - but once the call goes through a call queue it no longer passes the caller's ID along.

You should contact your provider and see if it is supported and they will let you know what parameters you should change.

Hey guys, I have the same issue, our provider has confirmed that this works and I have also tested this myself via another phone system however with 3CX and "OriginatorCallerID" enabled the callers ID is not forwarded on via the group, I have also tested this with a DID going to an extension that is forwarded to a mobile but no matter what it shows the CLI of the SIP trunk
