Wrong Caller ID being used for outbound calls

[Midd-Atlas]

Sometime last week, outbound calls started displaying the wrong caller ID for recipients and it is being flagged as spam. The caller ID is not one of our DIDs, but we discovered it is a part of the Authentication ID (SIP User ID) for our secondary trunk.

Hello @Midd-Atlas

It seems that you have already opened a support ticket regarding the reported behavior.

Please note that we have replied to your ticket with additional troubleshooting steps.

That said, in these kind of scenarios, you should confirm whether the issue occurs when using different outbound rules or only particular ones, as each rule may have a different Outbound Caller ID configured.

Additionally, does the issue affect all user extensions or only specific users? Please keep in mind that each user can also have an individual Outbound Caller ID assigned.

Since the issue affects all your calls, please also navigate to Admin > Voice & Chat > Edit your SIP Trunk > Options > Caller ID Control and review whether a Default Outbound Caller ID is configured and which value is assigned:



If any exists, you may delete it to then perform a new test.
