[Asterisk-Users] Delayed ringing on some SIP phones

[jurczak]

Why dont you make a special extension where you could provide the delay and 
the numbers you want to dial?

for example

exten => _900XXXXX,1,Wait(${EXTEN:4:2})
exten => _900XXXXX,2,Dial(SIP/${EXTEN:5})

then in the incoming context you could dial 

exten => s,1,Dial(SIP/200&SIP/201&LOCAL/90015300&LOCAL/90015301)

in the above example 200 and 201 extension will ring immediately, and 300 and 
301 will start ringing after 15 seconds.
after to 900 the first two digits are for the delay before start ringing
and the last three are the extension that should be called.
