Hi Jan, Thanks for the quick response. > there is definitely no limit on the number of registrations in GnuGk. It is what I assumed. I can now see I have more than one problem. The Quintum ASM400 gateway below will register to my secondary GnuGk, which is the same config as the primary, except for some IPs. Primary: 2010/02/12 12:27:37.159 1 RasSrv.cxx(354) RAS RRQ Received from xxx.xxx.177.20:20001 2010/02/12 12:27:37.159 2 RasSrv.cxx(394) RRJ|xxx.xxx.177.20|xxx.xxx.177.20:h323_ID|gateway|securityDenial; 2010/02/12 12:27:37.160 3 RasSrv.cxx(236) RAS Send to xxx.xxx.177.20:20001 registrationReject { requestSeqNum = 10681 protocolIdentifier = 0.0.8.2250.0.3 rejectReason = securityDenial <<null>> gatekeeperIdentifier = 5 characters { 0047 006e 0075 0047 006b GnuGk } } Secondary: 2010/02/12 14:06:40.621 1 RasSrv.cxx(354) RAS RRQ Received from xxx.xxx.177.20:20001 2010/02/12 14:06:40.622 3 RasSrv.cxx(236) RAS Send to xxx.xxx.177.20:20001 registrationConfirm { requestSeqNum = 10876 protocolIdentifier = 0.0.8.2250.0.3 callSignalAddress = 1 entries { [0]=ipAddress { ip = 4 octets { xx xx 22 59 .."Y } port = 0 } } I'm not sure what to look for with the "securityDenial" in the gateway config. Also, I have a Quintum AXM1600 gateway that logs as: 2010/02/12 14:11:45.610 1 RasSrv.cxx(178) RAS Could not decode message from xxx.xxx.55.9:20001 2010/02/12 14:11:48.622 2 RasSrv.cxx(175) RAS Read from xxx.xxx.55.9:20001 I have more gateways that don't seem to appear in the logs, yet. Thanks.
