Re: Unable to establish ISDN BRI.

here, try out this config;

interface BRI0/3/0

no ip address

isdn switch-type basic-net3

isdn point-to-point-setup

isdn incoming-voice voice

isdn static-tei 0

!

interface BRI0/3/1

no ip address

isdn switch-type basic-net3

isdn point-to-point-setup

isdn incoming-voice voice

isdn static-tei 0

Please also 'compand-type a-law' under voice port. Of course replace the interface numbers with your own.

Re: Unable to establish ISDN BRI.

Hi,

Any chance you need "isdn static-tei 0" in that location? Common for DID and multi-BRI provisioning.

In any case, enable "debug isdn q921" and "term mon" to see what's going on in there.

Hope this helps, please rate post if it does!
