FreePBX or Asterisk GUI? Which version of AsteriskNOW?
Whilst I haven't used AsteriskNOW, I can think of no reason why it would arbitrarily delay ring detection.
It might do so for one ring if you have US type caller ID enabled.
It probably would do if distinctive ring detection was enabled - maybe that is always on.
The public network may be providing you with ringback tone considerably before it applies ringing current to the destination. That might be particularly likely if calling from a mobile.
Have you tried using a standard phone, on the PSTN line, to see when it starts ringing?
Have you checked that there isn't a delay in the set up of the call to the phone (set verbosity to at least 3 and see how long it takes between the Dial application call and the start of the phone ringing).
Otherwise there would have to be a Wait application call at the start of the dialplan. I would expect no more than a second, if any at all.
