When a Branch Gateway is in SLS mode, three call appearances, each with limitations, are supported:
Note:
First
, second
, and third
, refer to the order in which you use call appearances, not the order of the Call Appearance buttons on your phone.
For example, User A chooses the third call appearance to dial User B, and then User C calls User A, which is sent to the first call appearance. In this situation, a subsequent inbound call to User A will be denied (busy) because the first and third call appearances are in use, and the second call appearance is only available for outbound calls.
