[Bristuff-users] "Cause 34" on free channel

[Gunnar Schaller]

Hello,
Thank you very much for your help. As discussed on Asterisk-Tag in
Berlin there is definitly a problem with power-saving mode/ layer 1
not active the whole time. So if the qozap driver handles it correctly
the failure is maybe in Asterisk or libpri...
I now commented the line 1005 and 1010 ("if (debug > 2)") in qozap.c
out so the qozap driver prints every try to re-activate the layer 1.
It would be fine to have somebody else trying this. We need the error
again to find out what happens in the inside of
Asterisk/libpri/zaptel/qozap. I hope we can fix it.

Thanks,
Gunnar
