Feature Definition
When user A uses a phone to send a call request to user B's phone, a voice call is initiated. When user B answers the call, a voice call is set up. Either party can end the call at any time.
The user who initiates a call request is the calling party. The user who answers the call is the called party.
In a voice call, either the calling party or the called party must be a PBX user.
ϒ⁄If both parties are PBX users, the voice call is an internal call.
ϒ⁄If only one party is a PBX user, the voice call is an external call. In an external call, a trunk is used to connect to the peer switch and then to the other party.
