What have you set the
PSTN Dialing Delay:
on the PSTN Line tab (logged in as admin advanced) ?
Mine is set to 1 and it works well.

delaybetweenanswering and ringing
Hi Jean-Michel,
We did actually try the 'r' option, but it has no effect, as Asterisk will
only supply ringing until the dialed SIP extension answers, which it does
immediately. The 4 second delay occurs between when the SPA-3000 answers
the SIP call and then places the PSTN one. I believe that the ringing tone
is provided by the PSTN at that point.
Regards,

You could use the 'r' flag in your Dial() command to simulate a ringing
tone instantly. This is less than ideal though. Have you done some SIP
traces (using ngrep for examples) to look when the SIP 'ringing' signal
is actually being sent?
Cheers,
Jean-Michel.
