Description:I don't what the pseudo channel does, nor whether it is represented by channel -2, but immediately after starting * dahdi show channels shows me three channels (this is on a BRI wcb4xx-like card), dahdi restart talks about unregistering channel -2 which is odd and then dahdi show channels tells me pseudo has gone.

Was it important? Why was it there in the first place?

Could you please provide the full trace from a 'dahdi restart'?

Note: 'module reload chan_dahdi.so' does not add or remove channels. 'dahdi restart' removes them all and re-adds them.

I don't understand what more I can get - how do I get a "Full Trace"?

I haven't mentioned unloading any modules you can see from my attached "additional Information" what I did.

You seem to have no channels generated on 'dahdi restart' . Yet we don't see any error.

What is the output of:

 logger show channels

Can you get 'verbose', 'notice' and 'error' logged to the console as well? Could you repeat the same with verbosity level 3?
By: Tim King (timking) 2009-03-06 05:15:42.000-0600

The only "error" is that the Pseudo channel goes away.
This time on a system with one each FXS & FXO
