Call Manager router failover

Hi

We have two routers at each of our sites, one has our WAN connection
"xx-2651-1", the other has our ISDN30 "xx-2651-2".  If our ISDN 30 router
hardware fails, we physically move the ISDN 30 cable from "xx-2651-2" to
"xx-2651-1".  In CM 3.2 this automagically worked as we have both routers
configured in CM's "Route Group config".

Now in CM 4.2(3) after an upgrade this doesn't seem to work any more; the
only way to get this to work is to manually move the cable and then swap
the priority of the two selected devices in CM's "Route Group config",
then all calls route in and out as expected.

If we don't swap the priority the below happens:

1) external > inbound are accepted and routed as normal
2) internal > internal are accepted and routed as normal
3) internal > external get an engaged tone
4) "csim start" simulated calls from the router i.e internal > external
work fine as well

Any ideas would be appreciated.
