[cisco-voip] Call Manager router failover

[Sam Hall]

Hi

We are using an H323 gw

Yep configured as you mentioned, see URL's below with screen print of 
Route pattern, Rlist, Rgroup gateway config... remember this manual 
failover worked fine when we were running v3.2

Thanks

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.
