[asterisk-users] Zap channels for HFC-S PCI card not responding

Hi list,

After upgrading from Asterisk v1.2 to v1.4.14, all kinds Zaptel error
messages related to my HFC-S PCI card disappeared, but now I can't
access the card's resources because it always seems to be busy. Any
idea why?

Thanks,

Jaap

PS -- Below is some info regarding my configuration.

6 channels to configure.

/etc/asterisk/zapata-channels.conf after running "genzaptelconf -sd -c nl":

group=0,12
context=from-pstn
switchtype = euroisdn

/etc/asterisk/zapata.conf (supposed to work in the Netherlands):

Abbreviated /etc/asterisk/extensions.conf:

Any attempts to call out result in the following CLI output:

Not a good idea, since that results in...

the channels disappearing altogether!
