Environment is CUCM v7.1.3 with CUC v7.1.3. Multiple sites with 911 mgcp gateways (fxo) at smaller sites, PRI gateways at larger sites.
Having problems with misdialed 911 calls previously handled by introducing delay (inter-digit timeout) before routing calls. Wondering about configuring callhandlers in Unity Connections with greeting "You have dialed 911, stay on the line to be connected to emergency services" and then transfering the call to 911. The hurdle is how to route the calls coming from CUC to the correct gateway.
Any suggestions would be appreciated.
