Help is on the way:)

This is quite simple to achieve on Sipura units.  There is a parameter 
called

Dial Tone:   350 at -19,440 at -19;10(*/0/1+2)

It defines the frequencies and duration of the tone.  The "10" you see 
near the end is the duration.  Simply change it to 60 like this and 
you're done:

Dial Tone:   350 at -19,440 at -19;60(*/0/1+2)

I just tried it and it works like you want it.

Hope it helps.
