What is mobility extension? How to configure it?
Mobility extension is used to bind mobile number with an extension, so this mobile number will have the corresponding extension’s call privilege, such as: make internal calls, make outgoing calls, and play voicemail unread, etc. When the user uses this mobile number to call into S-Series VoIP PBX, the PBX will treat it as the corresponding extension, and he/she will hear the dial tone.
To configure mobility extension, follow the steps below.
1. Click Settings → PBX → Extensions, go to extension edit page. Click “Edit”.
