[asterisk-users] PRI device is down

[Elliot Murdock]

Hello,

My Digium wct4xxp suddenly stopped working.  Here are some of the logs:

zap restart
[Aug  3 10:02:55] WARNING[15050]: chan_zap.c:903 zt_open: Unable to
specify channel 1: Device or resource busy
[Aug  3 10:02:55] ERROR[15050]: chan_zap.c:7164 mkintf: Unable to open
channel 1: Device or resource busy
here = 0, tmp->channel = 1, channel = 1
[Aug  3 10:02:55] ERROR[15050]: chan_zap.c:10471 build_channels:
Unable to register channel '1-15'
[Aug  3 10:02:55] WARNING[15050]: chan_zap.c:9768 zap_restart: Reload
channels from zap config failed!

I can supply other logs, but what can be wrong with the card/system?

Thanks,
Elliot
