At present, I have this element of the dial plan to reach the PSTN line on a
Linksys SPA 3102

|<9,:>x.<:@gw0>|

Dialling 9 gives the PSTN dial tone but it is a simulated one generated by
the ATA.

I was wondering how to obtain the actual BT dial tone rather than the
simulated one.

I've seen posts on the subject saying it can be done but without any detail
as to what parameter or component of the dial plan is needed.

Incidentally, the simulated dial tone times out after 3 seconds as defined
by the "Interdigit Short Timer" parameter but I don't want to extend this as
it would delay sending of a dialled number.

Any comment would be much appreciated - Cheers from Mike.
