Hi Erik
Fixed now, thanks for your help though.
The router configs were correct, but one of our CMs had the following
service parameter set to true, (the other was false). I've set them both
to false now and tested, It now fails correctly between the two routers on
site.
"Stop Routing on unallocated number - this should be set to false"

Sorry - can?t be of any help other than to say:
I had several issues with ver 4-2 ?? mostly with huntgroups and attendant
console so it might be worth while looking at getting the latest service
release if your problem is related to bugs..
We upgraded a while ago and things are looking better for us

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.
Sam
