It is possible. It's a good while since I did it but I believe the dial
plan is something like:

<9:>S0<:@gw0>

Then on the PSTN Line page you need to change the default dial plan for
the VoIP-PSTN Gateway to "none". The setting is called "Line 1 VoIP
Caller DP" if I remember correctly.

I originally worked this out for a customer who was connecting SPA3000s
to PBXs and wrote this document which might help you even more:
