In example 1 and 2 the phone will be ringing sequentially, one by one, with 15 seconds ring time each.
Example 1:
exten = 1001,1,NoOp(Operator)
same = n,Dial(SIP/101,15)
same = n,Dial(SIP/102,15)
same = n,Playback(vm-nobodyavail)
same = n,Hangup
Example 2:
exten = 1002,1,NoOp(Operator)
same = n,Dial(Local/5501@internal,15)
same = n,Dial(Local/5502@internal,15)
same = n,Playback(vm-nobodyavail)
same = n,Hangup
In example 3 and 4 all phones will ring all-at-one, with 20 seconds ring time.
Example 3:
exten = 1003,1,NoOp(Operator)
same = n,Dial(SIP/101&SIP/102,20)
same = n,Playback(vm-nobodyavail)
same = n,Hangup
Example 4:
exten = 1004,1,NoOp(Operator)
same = n,Dial(Local/5501@internal&Local/5502@internal,20)
same = n,Playback(vm-nobodyavail)
same = n,Hangup
