Do you have a sample configuration for VIC2-2BRI-NT/TE? This device is connected to a Cisco 2851 ISR and used for incoming and outgoing calls.

Thank you,

Thank you.

Hi, ISDN BRI by nature doesn't go down when unplugged. How many circuits do you have in trunkgroup ? There is a suggested config to work around that, but if you have one circuit only, isn't needed.

Thanks for your reply. I have 4 BRI circuits connected to these devices. All of them are member of the trunk group BRI-trunks.

What else am i missing?
