[RoutedMode]
H245Routed=1
I hadn't even thought of the TCP session timing out that quickly. UDP, definitely, but TCP timing out that fast just doesn't seem right to me (though it wouldn't be entirely suprising).

Alternatively, if that were the case, would this help?
sysctl -w net.ipv4.tcp_keepalive_time=15
By default, that's 7200 (2 hours), not 15 seconds.

My guess is that the H.225 TCP connection is being dropped forcing the DRQ
from GnuGk (shutdown the call). Hence the forceDrop reason
Generally firewalls will drop TCP connections after about 20 sec of
inactivity. The H.225 channel gets very little activity if not H.245
tunneled. Make sure there is nothing between the devices that could do that.
The only other reason is the Mirial side is deciding to drop the TCP
connection due to a timeout or something. You will need to check the config
and logs as well. You might need to consult mirial.
Either case the error is coming from outside GnuGk control.

Subject: Re: Question about disengageRequest
Thank you Jan!
My main skill is unfortunately SIP but on that side I can see the SIP
Invite, SIP OK and later SIP Ack which should mean that H323 has connected
the call?
I have tried to go through the Gnugk traces but have difficulties detecting
the source of the error.
I see:
maintainConnection = false
supportsAltGK = <<null>>
in the registration that looks bad.
In the sudden disengageRequest (from primary gnugk directly to Mirial) I see
a forceDrop as disengageReason. Without getting anything from the H323
client?

If it is OK with you I'd like to send you the gnugk traces directly (not
exposing real IP's), both the primary and alternative one together with my
gatekeeper configuration?
Only if that is OK of course! :)

Ämne: Re: Question about disengageRequest
Again, audio and video is no indication that the call has connected (and
would be past most of the message timeouts). You have to check for the
Connect message and check if the H.245 connection negotiated properly.

disconnects both sides. Primary gatekeeper has been "quiet" for about 20
seconds before this so something is absolutely happening!
