[Asterisk-Users] TDM400P FXS problem

[Sergio Garcia Murillo]

Hi

I'm getting strange problems with a fxs port of a didium TDM400 card.
>From time to time the telephone i've got plugged stop working correctly. I
pickup the phone and i got dial tone, but if i try to dial it does nothing,
as if it doesn't recognize de tones. If i press the flash key it works and
any key pressed later wroks also. The only way of making it work is
unplugging it and plugging it again till it works. 
Any ideas of what could be happening or at least which parameters in the
zaptel driver could i start experimentin with?
By the way, the phone if got plugged into is the standar phone that
Telefonica sells here in Spain, so i would like to make asterisk work with
that model.

 Greetings
