My setup is a bit different than Paul's but I'm struggling with the same issue.
I have:
EP1--(LAN)-->Proxy GnuGK--(WAN)-->State GnuGK-->EP2
EP1 can dial EP2 via Dialed Digits (E.164) just fine. However, when EP1 dials
EP2 by IP address the call fails because Proxy GnuGK attempts to contact EP2
directly which generates the "routeCallToGatekeeper" error. How can I route all
call signaling to another gatekeeper?
I'd appreciate any feedback!
My setup on the Proxy GnuGK is as follows:
[Gatekeeper::Main]
Fortytwo=42
Name=NWESD-GK1
ExternalIP=<GK IP>
[RoutedMode]
GKRouted=1
H245Routed=1

Subject: [Openh323gk-users] Calls by IP address fail to use proxy
I'm encountering a problem which may be related to Andrew Struiksma's
IP dialing issue.
I'm using GnuGk in proxy mode behind a NAT talking to GnuGk also in
proxy mode on a public IP address (diagram below), taking advantage of native
GnuGk firewall traversal. Calls made using DialedDigits addresses work fine in
both directions, proxy mode does what it's supposed to do. But when EP1 calls
EP2 via IP address, GnuGk #2 handles the routing and call setup, but then the
RTP streams (try to) go directly to GnuGk #1 (via firewall's public IP address)
- which doesn't work, of course.
This is true when:
1. EP2 is registered to a foreign gatekeeper and called via the
foreign GK IP address and DialedDigits
2. EP2 is not registered to any gatekeeper, and is called by its
public IP address directly
3. EP2 is registered to GnuGk #2 and called by GnuGk #2 IP
address and DialedDigits
EP1 à GnuGK #1 (gateway proxy mode) à |NAT Firewall|à GnuGk #2 (proxy
mode) à EP2
It seems that calling an external EP by IP address should be a common
operation, but I can't seem to make those calls proxy. Can someone help me to
get proxy mode to work correctly?
(There seems to be a some confusion here about how to make IP address
dialed calls in general in GnuGk; certainly I, for one, am confused. If someone
could lay out the general concepts, I'd be very grateful. In Radvision ECS, for
example, you can set the GK to accept calls by IP address never, always, or
from registered endpoints only - is there a GnuGk equivalent?)
Many thanks,
--Paul
