Connect ISDN phone to VIC2-2BRI-NT/TE

[Hunfiu12]

Hi all,

I have a 2811 router with a VIC2-2BRI-NT/TE. I want to connect a Swissvoice eurit 25 ISDN phone to the router, but when I configure the BRI 1/0/0 port in network side mode and connect the phone, the port doesnt bring up and the phone stay off.

The BRI 1/0/0 configuration:

no ip address
isdn protocol-emulate network
isdn layer1-emulate network
isdn incoming-voice voice
line-power

Im sure the phone is working correctly becaus its turn on if i connect it to an NT1 device.

Hopefully someone who's actually done this will chip in.  However what do you see under "sh isdn status" and from the debug "debug isdn q921"

I found the problem. The cable was wrong.
