Re: [hylafax-users] voice prompt playback before DTMF read?

["Ivan Petrov" <ivanp@xxxxxxxxxxxxx>]

Thanks Darren! It is all clear now.

Lee's development version works fine for me so far. I just got latest one 
from SF.net compiled and tested - it is ok.

I'd love to see this feature added to the release product at hylafax.org!

Regards,
Ivan
