[VoIP] DISA questions

[Jayson Smith]

Hi all,
I have a few questions about DISA. First, there's no way to use wav files
for dialtone, ringing, busy, etc. is there? Man I'd love to use old sounds
for these events!
Also, what, exactly, happens when a caller at a DISA dialtone doesn't dial
anything at all within the allowed time? I've just about figured out that if
an incomplete extension is dialed, it goes to a Timeout somewhere, but is
there a way to intercept a caller not having dialed anything at all? I'd
love to be able to play a "If you'd like to make a call . . ." recording,
then the off-hook tone.
Jayson.
