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

[Jaap Winius]

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.

Abbreviated /etc/asterisk/extensions.conf:

    exten => 1000,1,Verbose(1|Extension 1000)
    exten => 1000,n,Dial(SIP/1000,30)
    exten => 1000,n,Hangup()

    [phones]
    include => internal
    include => isdn-out

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

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

CLI> zap show channels:

       Chan Extension  Context         Language   MOH Interpret


the channels disappearing altogether!
