Hi Robert,
in the openLogicalChannelAck they are telling your GnuGk the RTP
destination port and a private IP doesn't work for that.
There isn't really much you can do about misconfigured endpoints other
than configuring it correctly. What you can do is provide a
H.460.18 enabled gatekeeper on a public IP and ask these folks to
register with it for the duration of the call.
Regards,
Jan
