前言

 * A call is placed in one or several call groups
 * A call comes to that Extension/Channel, it belongs to that Call Group
 * If a phone belongs in a pickup group that matches one of the call's call groups
 * call pickup typically only works WITHIN a technology
 * 0~63 groups
 * Default 係沒有 "call_group" 的

sip 的設定:

callgroup=1     ; 設定某一個 extension 在某 group
pickupgroup=1   ; 某 extension 可以拿某 callgroup 的電話

pjsip 的設定:

call_group=1
pickup_group=1

Requesting to pickup a call is done by two basic methods

    - by dialplan using the Pickup or PickupChan applications.
    - by dialing the extension defined for pickupexten configured in features.conf.

features.conf

pickupexten = *8
pickupsound = beep
pickupfailsound = beeperr

ringing sequentially

exten = 1001,1,NoOp(Operator)
    same = n,Dial(PJSIP/509,15)
    same = n,Dial(PJSIP/510,15)
    same = n,Hangup

ring all-at-one

exten = 1002,1,NoOp(Operator)
    same = n,Dial(PJSIP/509&PJSIP/510,20)
    same = n,Playback(vm-nobodyavail)
    same = n,Hangup
