[asterisk-users] Fast Busy Followup

[Rob Schall]

So I might have a bit of a more narrow question from my earlier one.

Previous, I had been wondering what would cause a phone dialing into a
DID that connects to the asterisk box to get a fast busy.

I've noticed the following message:
chan_zap.c: Ring requested on unconfigured channel 0/1 span 2

Any idea what would give me this error? And would this cause a fast busy?

Thanks again everyone for your help with this matter,
Rob
