[Asterisk-Users] problems with analog interface to PBX

[Dan Fernandez]

Steve,

Thanks for your respnose. The flash does seem to work. If I plug a phone on
the x100p I can hear with the x100p flashes. I then get a dialtone. The
problem is that when i try to dial again from that card, i get "cannot
create zap channel". It seems that because the line is now off hook, the
dial cannot proceed.

Thanks again.
