Attempting to setup redundancy on the gateways, in case of a failure. The digit analysis shows the call being delivered to the failover gateway with the 9, however a debug isdn q931 shows the call being delivered without the 9. Why would the digit analysis show the 9 being delivered, when it is not?
The failover gateway needs the 9 to be sent, while the main gateway does not. Primary gateway is connected to the PSTN and the failover gateway is connected to a PBX.
Clayton_PSTN_RL is the primary
PBX Routes is the failover
Here is the digit analysis:
