An outgoing call my fail. Depending on the cause the call fails with, a re-routing is performed.
Causes causing rerouting are:
- #1 "Unallocated (unassigned) number"
- #2 "No route to specified transit network"
- #3 "No route to destination"
- #18 "No user responding"
- #34 "No circuit/channel available"
- #38 "Network out of order"
- #41 "Temporary failure"
- #42 "Switching equipment congestion"
- #44 "Requested circuit/channel not available"
- #47 "Resources unavailable, unspecified"
- #49 "Quality of service unavailable"
This mechanism is implemented both in the PBX Gateway object and in the Trunk object as well as in the gateway level routing engine.
Re-routing calls which failed due to one of the first 4 causes (Unallocated (unassigned) number, No route to specified transit network, No route to destination and No user responding) may not always be desirable. There is a No Reroute on wrong No option available in the gateway routes to disable this. The relay (gateway) will not re-route on these causes.
