CM Fail back - Not Working.

mattsthe2

We are opening a very small new office and our MPLS connection will not be turned up soon enough.

The thought was the put a 2811, 4 pots lines in the 2811, a switch and 4 phones at this site and have the phones go into CM Failback mode.

But the phones don't go in to CM Failback mode.
The phone does grab a DHCP address from the 2811 though.

We have many other sites that CM-Failback works and im using the same config for this router.

What could be causing my issue?
This router has never been connected to our network before.


CM-Failback config

have the phones and gateway been registered to the CM at some point in time?

negative.

This is a new temporary network (new LAN IP's), with a new IOS config. The router might have but again, new IOS software and a new config.
The 4-phones probably have.

I'm thinking that the fact the router hasnt been registered before with CCM is causing this issue.
I was thinking about registering the router (at corporate) and then shipping down the equipment and hoping it goes int SRST mode.


It would only be running for about 3 days while they move offices.
(Very small office by the way).
