[asterisk-users] Delay before ringing from PSTN`s call

[John Novack]

You need to make sure your (DAHDI or ZAPTEL ) is set up properly for your country's CLID protocol
In the US CLID is sent between the first and second rings, and with a proper configuration Asterisk waits a ring before processing the call
Other parts of the world use different methods and protocols
You will need to dig into that first.
