I am trying to configure my cisco CME to use my BT ISDN connection. I have attached the configs. When I try and dial out, by pressing 8 then the number.
(destination pattern set to 8.T) I get an unknow number error on the phone. When I debug the dial peers it says no dial peer matched.
Can anyone help me?

Hi
If you have a BT ISDN why do you need to emulate the network side of the connection?
interface BRI0/0/0
no ip address
isdn switch-type basic-net3
isdn point-to-point-setup
isdn incoming-voice voice
isdn layer1-emulate network
isdn protocol-emulate network
!
Is your ISDN even up at this point? If not, the dial-peers will go down as well.
Do a show isdn status, and post the result.
Also a show dial-peer voice summary.

Thanks for your reply
Only just add:

isdn protocol-emulate network
Removed them now.

Just tried a test call and it allowed an out going call? all a bit strange.
Now when I try and dial in I get told "the call will be disconnected"
I hoping that the Auto attendant will answer so I can dial an extension in.

Hi
Outgoing calls are working as you have corrected your ISDN interface configuration.
If the interface isn't up (which it wouldn't have been before you removed those commands) you won't get calls either way.
Re: inbound calls, start by doing a debug isdn q931 and placing a call in. This should reveal what numbers are being presented by BT.
