Re: [Openh323gk-users] Call Route Failover (ASAP)

[Ali K. \(Intelicom\) <al...@in...>]

Is the following scenario possible? (basically stating, skipping some
details, just a draft in sprit of telling what's beyond my mind)

1. Terminal --> GK: Call Request
[After ConnectionEstablished]
2. GK <-- Radius: Array of RedirectionIPs (=GW.1, GW.2, GW.3, ..., GW.n)
3. GK: Try GW.1
3.1. Catch if GW.1 returns FAIL signal (on EventError)
3.2. Try GW.2
and so on

Some more thoughts in the case you would like to implement this in gnugk.

- Of course, when implementing this feature in gnugk (instead of an external
application) you could get much more control over the routing decision and
espacially more information about the reject causes
- If i get it rigth, this feature would require routed signalling or proxy
mode. It wouldn't run in direct signaling mode, because you need the Q.931
signalling to allow smart routing (partial rerouting) decisions
- you would have to react on quite a number of different Q.931 cause values
to decide on how to react
- since implementation on Q.931 causes differ from device to device, for a
general implementation it would be very usefull to also implement a Q.931
cause mapping table (to allow mapping of Q.931 cause values to internal
gnugk reject reasons).
- one could think to implement this feature in a general manner, no matter
if the called endpoint is a terminal or a gateway. Like this there would be
the possibility to build a kind of partial rerouting also for endpoints
(i.e. allowing to "take calls back" and terminating them on a different
endpoint, i.e. a voice mail system).
