Outgoing CLID suddenly showing the DID when it never did before.

[NickEmpireComm]

I've been using and configuring 3CX for some time now.

Previously, whenever we wanted to have anonymous caller ID we would leave the "Caller ID" field on an extension blank as well as in the outbound rule. The outbound call would then appear as "Anonymous"

However, for some reason out of nowhere the outbound caller ID is now displaying and I'm trying to figure out where it is getting this information from. I've run a packet capture and 3CX is sending the CLID in the invite. The "Remote Party ID - Calling Party : User Part" is set to ""OutboundCallerId" Outbound Caller ID Taken from Extension Settings in Management Console". I've checked every single extension and they all have no caller id set, but some how it still displays.

The current SIP trunk is as follows
- Country: Generic
- Provider: Generic SIP Trunk
- Registration: None, IP based (we host our 3CX customers in our Co-Lo which is local to our SIP Trunk service)

Any ideas where this is coming from would be greatly appreciated.

Hi @NickEmpireComm

The PBX will always try to send out an Caller ID if available. The option "OutboundCallerId" Outbound Caller ID Taken from Extension Settings in Management Console" will look for an outbound caller ID in the extension settings and if it does not find one it will use the main trunk number of the trunk. This has always been the case.
Also if everything is empty the PBX will not send anonymous calls, this is filled in by your Provider as it does not recognize the caller ID.

You can find more details on how outbound calls work from 3CX here.

Thank you for this clarification.

Up until a few weeks ago this is how it was working. We not only host the 3CX instance for the customer but we are also the service provider.

The DID number must be set somewhere, 3CX can't just pull it out of thin air. Could it be set in the phone/device itself? That location along with the extension setting (that you've already checked), the trunk setting and the outbound rules, are the normal places CID is taken from. This is in addition to a number being added by your provider,.if you don't send one.

Did you come up with a solution or a reason a 3CX hosted Service suddenly changed?
In the last three weeks we have also lost out Extension based CLID.
DIDlogic now shows "+Anonymous" as the caller ID even when set the CLID in the extension or even when i set as the outbound rule. Seems like 3CX update has lost its CLID output

Did you check the 3CX Activity log (Verbose), to see, if what caller ID, being sent to your provider, has changed?
