You can set a maximum number of sessions that an extension can receive in [Max inbound sessions] under the Brekeke PBX user settings. Call sessions are counted either from the beginning of the conversation or when the phone begins ringing until the phone call is terminated.
1. Unlimited Sessions
When unlimited sessions are set at [Max inbound sessions], incoming calls will ring the extension even if the extension is in one or more sessions already. When the call remains unanswered by the extension after the specified (Ringer time), it is either forwarded to the destination set at [Forwarding destination (No answer/Busy)], or it executes that SIP UA’s send response, such as “busy,” “reject,” etc.
2. Limited Sessions (0-6)
If the callee’s extension already has the maximum number of sessions, as set at [Max inbound sessions], and all of those sessions are busy, an incoming call will be forwarded to the destination set at [Forwarding destination (No answer/Busy)]. If there is a session with ringing status, an incoming call will stay in pending status until all sessions are occupied or until there are no sessions remaining.
3. Using Maximum Session Setting
The Maximum Session setting may be useful in the following ways:
Preventing missed calls
By setting [Max inbound sessions], users can avoid missing calls. When multiple calls are coming in at the same time, all calls except the first one are forwarded to the destination set at [Forwarding destination (Busy)].
Setting the preferred number of simultaneous calls
For SIP UAs that have the ability to handle multiple sessions, users can limit the preferred number of simultaneous calls in order to make other lines available for outgoing sessions.
