asterisk users - Jan 2005 - Firefly reject problem - it just keeps ringing

Hi,

when I press reject on Firefly, another end hears congestion, but I'm still
listening to ringing...

Also how you determine which version of Firefly you have?

I also don't understand licence completely and would like to get this
answer - can I distribute Firefly to commercial users if I don't charge
anything ?

Regards,

Rob.
