Re: Alternate gatekeepers and neighbors question

[Andras Kovacs <akov@xxxxxxx>]

Jan,


Thanks. This will help. Would make sense to include 1-2 sentences on 
this in GnuGK manual.

Yes, obviously there are no ARQs between neighbors. I didn't mean that.

So, in best case, my top level GK will receive two LCF messages from 
downstream partners. One can be ignored, etc. Both contains the same IP. 
This sounds good.

How about routed mode? I did not mention we employ routed signaling 
here. Where the flow of signal will go through when a call drops in from 
an external network to my top level gatekeeper? Will this also forward 
Q.931 down to both GKs? First SETUP message reaching the endpoint will 
win the race?

Thanks.

Andras
