Say I have 2 gateways gw1 and gw2. gw1 is setup as an h232 gateway with 8 POTS lines. And gw2 is set up as MGCP with a PRI. I would like to be able to failover outbound calls to gw2 if all the lines POTS lines on gw1 are in use.
Currently I have the Route List set up with both gw1 and gw2 in it so if they where both mgcp gateways I think it would work. However the h323 gateway doesn't seem to send any thing back to call manager to let it know it's full. So when a call is placed when all the POTS lines on gw1 are full the caller just gets dead air.
Does anyone know if there is a way to make this work?
