As usual, if the extension of your colleague rings, but he or she is not beside the phone, you can pick up the call.
In elastix, there are two methods to pick up the call of anybody else: *8 and **.
*8 is used when just one extension is ringing in your office.
** is used when some extensions are ringing at the same time, at that time, you can press **+the extension number to pick up the call of the specific extension.
About how to use the *8, you need to make sure the number of your pickupgroup is same with the number of the other ones’ callgroup.
extension 5001:callgroup 1 pickupgroup 2
extension 5002:callgroup 2 pickupgroup blank
so 5001 can pick up any calls whose callgroup number is 2, such as 5002, but 5002 cannot pick up any extension, because its pickupgroup number is blank.
About how to use **, let us take an example, when 5001 and 5002, 5003 are ringing at the same time, you can press **+5001 to pick up the call of 5001, or you can press **+5002 to pick up the call of 5002 and so on.
