Re: send prefix

Ah. That explains some things. One thing though that I never understood and it is not mentioned in the manual is how does GnuGK act when Type=Gateway versus Type=Terminal? 

Also, can you both neighbor with a gatekeeper plus list it as a parent? I'm wondering if I were to do that if it would solve the trouble I'm having with dialing some end points via IP address and getting the routeCallToGatekeeper and facilityCallDeflection issues.

Subject: Re:  send prefix

The idea of the parent gatekeeper is that it handles everything that
you can't handle locally. So when a call reaches the 'parent' policy,
because the other policies couldn't handle, it will always try to send
it to the parent gatekeeper (with an ARQ).

Since an endpoint can only be registered to one gatekeeper max, there
isn't any selection mechanism between parent gatekeepers.

However, if you really have to limit the parent gatekeeper to a certain
prefix, you can install a different policy chain for that prefix.

For example if only prefix 002 should go to the parent and you have a
local catchall for all other calls, you could do this:

[RoutingPolicy]
002=explicit,internal,parent
default=explicit,internal,neighbor,catchall

But I would  strongly suggest not to define too many different routing
chains. Its gets confusing pretty quickly.

Regards,
Jan

However, I'd love to be proven wrong since that would be a nice alternate way to "neighbor." I used to use the [Endpoint] section to specify a gateway however that didn't seem to allow me to do everything I wanted to do including specify my own extensions within our state dialing plan. I'm still struggling with a few issues but so far prefer this method (#2).
