Hi all! I am having a bit trouble solving one task from my supervisor. We have a few phones in a call group with setting to ring all if there is a call on any of them. He asks me if it is possible to call from outside phone on specific extension by dialing the number, and then the number of extension. For example, the numbers with extensions are 111-753159987, 222-951123963, 333-741159987, 444-852369741. If you call on any number, all phones connected to these extensions will ring, but is there a possibility to call only that one specific number without ringing all the others? When i would only like to call number 951123963?
