I have one FXO 911 line setup at multiple locations. Basically if someone at a firestation makes a 911 call. I have their calling search space set to a group for that building. That way 911 or 9911 calls are passed out the single FXO line I have for each building.
I need a failover basically if the 911 line goes down for any reason, It will use the PRI which is not located at the building but at the main building handling all the PRI lines. I have this setup in the Calling search space list. Basically 3 partitions.
So the first partition would be the fire station, next one would be the main building with the PRI. The correct route patterns are linked to this partition.
When I disconnect the 911 line to test this redundancy out. CCM doesnt seem to check if the line is working before trying to pass the pattern, so I come up with a busy signal. If I remove the firestation partition, calls work correctly to the next location. Doesnt seem to failover to the PRI. Any possible way I can make CCM check the analog fxo line then rolling the call over to a PRI ?
Also I have another question if this would help if 2 people in the same building call 911 with only 1 911 line in that building to pass person #2 that is calling 911 out to the PRI.
Sorry for it being so long.
Yes the second endpoint needs to be a member of the hunt group. A second partition will not send the second call to the applicable endpoint. The outgoing call will hunt through the list and if the FXO is the only endpoint in the hunt, it will not know to hunt to the pri. Add the PRI to your hunt and see how that goes.
Are you sure you are not using H323? If you sent it right to the gateway and the gateway shows as unregistered that sounds exactly like what you see in ccm for h323.
