Feature Request: Add Department Name as an Outbound Caller ID Source

[MBergeron]

I would like to request the addition of Department as a selectable source for the outbound Caller ID name.

Currently, 3CX allows us to select the Caller ID name source from the following options:

• Custom
• Default
• Line ID
• Line Number
• Auth ID
• Extension Settings

I would like to see an additional option:

• Department

When selected, 3CX would automatically use the name of the department assigned to the extension as the outbound Caller ID name.

Why is this important?​

This feature would be particularly valuable in multitenant environments, where different departments or tenants need to present different caller ID names when making outbound calls.

It would also benefit organizations with multiple departments or business units that want to display different caller ID names without having to provision and manage multiple SIP trunks.

Many other PBX manufacturers already offer similar functionality.

Expected Benefits​

• Simplifies outbound Caller ID management.
• Eliminates the need for multiple SIP trunks solely to provide different caller ID names.
• Makes multitenant deployments more flexible and scalable.
• Allows administrators to manage caller ID names centrally through department settings.
• Reduces configuration complexity and ongoing maintenance.

Ideally, the department name would be inherited automatically from the extension's department assignment, avoiding the need to manually configure the caller ID name on every extension.

I believe this would be a valuable addition to 3CX, especially for service providers and organizations managing multiple departments or tenants on a single PBX.
