Assistance with Departments and users configs

[john.fire-it]

Hi everyone, need some assistance with the setup of departments and user configs

Users work in different departments in the same building.
Have the following departments
Admin
Accounts
Sales

Reception queue gets main incoming calls then transfers to extension directly i.e. to 101 or 102 depending on where the caller wants to reach

Extensions are grouped per Department

If call is transferred to a user that is not at their desk another user in the department can pickup the call, got settings enabled that department users can only pickup calls in their department.

Weird issue is internal calls from extension to extension within each department works but when they try to dial an extension in a different department they get a line invalid error, this error seems to be mostly on wireless phones running on a dect manager

Running yealink W80DM firmware 103.85.0.25
Wireless phones yealink W56H 61.85.0.45

Please assist with settings that need to be configured for extensions in departments to call extensions in other departments

If this PBX is configured as an MCM (Multi tenant) they will not be able to contact other departments directly.

On a normal 3CX System, without MCM all extensions should be able to connect to other extensions without any configuration, unless those extensions have exception rules blocking calls from a certain extension, or range of extension numbers.
