I see several things in your configuration that may be causing the issue:
- I see a dialer-group configured under the interfaces but I do not see a dialer-list configured. With no dialer-list there will be no "interesting traffic" and the ISDN will not activate.
- I do not see anything configured at the branch that tells the ISDN what number to dial, something like dialer map.
- When you configure the serial interface with backup interface it puts the BRI into a special standby state. The BRI will not activate (it will not initiate a call and it will not answer a call) unless there is a failure of the primary interface (serial in your case). So how are you attempting to test the BRI? If you shut down the serial interface the BRI will not activate (IOS assumes that if you shutdown you intended to stop communication and will not activate the BRI). So you need some real failure of the serial (unplug it or something) for the BRI to be able to activate (even for a test).
