Cisco 2611XM + HSRP + ISDN failover

Hello!

I am considering such configuration:

2 x ( c2611xm, 8bri, 2xETH) that are running HSRP on bridged ETH.

int range fa 0/0 - 2
bridge-group 1

int BVI1
ip address 192.168.0.1 255.255.255.0
standby timers 5 15
standby preempt
standby authentication CievHSRP
standby ip 192.168.0.5

Now I have lets say 1 ISDN line that I'd like to connect to both
routers at once. Why? When one router will fail another will pick-up a
connection...

I assume/I wish that only HSRP active router will pick-up a dial-in on
ISDN? (in case when both routers are up and running?)
Is it possible to acheive it?
