> We are using a digium card (TDM400) with asterisk for our access to the
> PSTN. Initially when the server starts, all the zap channels on the card
> are in the "onhook" state. As soon as a channel is used (for inbound or
> outbound PSTN calls) the corresponding channel goes into "offhook" state,
> and stays in "offhook" state, even after the call ends; Asterisk log shows
> that the channel was hungup. Most of the time, the channel is still usable
> to make more PSTN calls, even though it shows in "offhook" state.
> Occasionally the channel becomes unusable for making PSTN calls (usually
> channel 1). The symptom is Asterisk and the client show the PSTN call was
> established, but the destination PSTN number never really receives the
> call. 
> 
> Shouldn't the channel go back to "onhook" state once the call hangs up? Is
> the persistent "offhook" state causing the channel to eventually become
> unusable?
