Groups
These options define who is allowed to pickup our calls, and whose calls we
are allowed to pickup
Call Group: Set the Call Group that the extension belongs to.
Similar to 'Context' grouping, only this option sets to which call group the extension belongs (ex. 3)
Pickup Group: Set which groups the extension is allowed to pickup by dialing '*8'. (ex. 4)
TIP: Grouping works only within a technology (SIP to SIP or IAX to IAX)
Example:
Extension A:
Call Group = 1
Pickup Group = 3,4
Extension B:
Call Group = 2
Pickup Group = 1
If A is ringing, B can pickup the ringing call by dialing '*8'.
If B is ringing, A cannot pickup the ringing call because B's Call Group = 2, and A can pickup only Call Groups 3 and 4.
NOTE: To be able to select Call Group and Pickup Group they have to be assigned to the tenant in Settings -> Tenants -> edit tenant -> Numbering Defaults (section) -> Call groups/Pickup groups.
