Failover Based on Telephony Cause Codes

„

Gateway failure during an active call by disconnecting the PSTN 

cable.

Applications needing specific information about a call failure can use 

the cause codes reported by BfvLineTerminateCall(). However, using 

cause codes to determine failover scenarios is complicated. In most 

cases, the cause codes supplied by the gateway are  

manufacturer-specific and depend on the protocol being used. 

Therefore, if you use any particular code in determining a failover 

scenario (where re-routing should occur), you should consider the 

context including the protocol and the gateway manufacturer.
