[Asterisk-Users] Problem with asterisk and zaphfc

[Massimo De Nadal]

Hi everybody,
I have a problem using zaphfc. When I start asterisk after 8-10 seconds I
get the message "Primary D-Channel on span 1 down" and my isdn modem stops
to work.
If I place or receive a call before this message all works really fine (even
if the call is very long), but when I hang up, after a few seconds I get the
message and the modem crashes.
Stopping and restarting asterisk solves the problem for another 8-10 seconds
:-(
Thank you for any suggestions....
