I have an ISDN E1 with 10 lines.
I can call out ok, but when I try to dial–in I get the dead tone on all numbers.
I’m using CCA to configure with software v8.2.0
PSTN trunks
Primary-net5 for UK
The default time slots 1-10
Ringing in – dead tone
Ringing out – ok
No error received on CLI when Inbound numbers are dialled.
When I change the time slots 1-31
Ringing in – dead tone
Ringing out – ok
Same results
But when I change the time slots to 5-16
Ringing in – engaged tone
Ringing out – ok
I receive this error message on the CLI:
000136: Oct 18 16:00:00.463: %ISDN-6-CHAN_UNAVAILABLE: Interface Se0/3/0:15 Requested Channel 1 is not available
Any help would be appreciated

To begin with, how many channels are you leasing from telco ?

Configure ten timeslots and post the complete q931 trace.

Thanks, I think we have found the problem.
We were using CCA version 3.1.(1) to configure (as insisted by Cisco support).
The ‘AA PSTN Number:’ box does not display in the CCA but the number does appear in the cli.
I have now gone back to CCA version 3.0.(1). Straight away the AA number appears, but it does not work unless you change it. Then re-enter the details and reconfigure all incoming dial plan.
Once again thanks for your interest.

In my opinion, using CCA is wasting time. Good that you have have solved anyway.
