Hello,
We have a small VoIP network based on GNUGK and the
scenario is like this: our customers are sending the calls in our main
gatekeeper (only routed mode, not proxy) from where we route the calls
to several gateways in different locations. For some of the gateways we do
not have public IPs and they run on private IPs behind NAT (linux servers). So
we are running secondary gatekeepers registered to the main gatekeeper in
proxy mode on the NAT boxes.
The problem is if two of the gateways behind the
proxy gatekeepers are rejecting the calls when there are no more channels
available the main gatekeeper (and even the customer gk when they are sending
from a gnugk) is not trying another failover route. So, after two proxy reject
the call is dropped no matter what other failover routes are
available.
I have tested several scenarios with a customer
also using a gnugk and when I route the calls to gateways without proxy in
front of them the issue does not occur.
We are running GNUGk 2.2.7.
customer gk -> main gk -> proxy gk ->
gateway
main gk config:
..........
