Has anyone had any luck getting Asterisk 1.6.2.13 to register to a Tandberg Gatekeeper? The logs on the Asterisk end seem to show that the registration request is sent, and the Tandberg Gatekeeper responds. However, the response doesn't seem to be what Asterisk was expecting. Here is my ooh323.conf, followed by the relevant portion of the h323_log: [general] port = 1720 bindaddr = 10.4.16.45 h323id = AsteriskVM e164 = 1200 callerid = Asterisk faststart = yes h245tunneling = yes gateway = no disallow=all allow=ulaw dtmfmode=rfc2833 gatekeeper = 10.4.48.15 AllowGKRouted = yes AcceptAnonymous = yes progress_setup = 3 progress_alert = 8 tunneling=none 11:27:28:163 Trace File: /var/log/asterisk/h323_log 11:27:28:163 FastStart - enabled 11:27:28:163 H245 Tunneling - enabled 11:27:28:163 MediaWaitForConnect - disabled 11:27:28:163 AutoAnswer - disabled 11:27:28:163 Terminal Type - 50 11:27:28:163 T35 CountryCode - 1 11:27:28:164 T35 Extension - 0 11:27:28:164 Manufacturer Code - 71 11:27:28:164 ProductID - objsys 11:27:28:164 VersionID - v0.8.3 11:27:28:164 Local signalling IP address - 10.4.16.45 11:27:28:164 H225 ListenPort - 1720 11:27:28:164 CallerID - Asterisk 11:27:28:164 Call Establishment Timeout - 60 seconds 11:27:28:164 MasterSlaveDetermination Timeout - 30 seconds 11:27:28:164 TerminalCapabilityExchange Timeout - 30 seconds 11:27:28:164 LogicalChannel Timeout - 30 seconds 11:27:28:164 Session Timeout - 15 seconds 11:27:28:164 Gatekeeper Client Configuration: 11:27:28:164 Gatekeeper mode - UseSpecificGatekeeper 11:27:28:164 Gatekeeper To Use - 10.4.48.15:1719 11:27:28:164 H323 RAS channel creation - successful 11:27:28:164 Ras message encoding - successful 11:27:28:164 Sending RAS Message = { 11:27:28:164 gatekeeperRequest = { 11:27:28:164 requestSeqNum = { 11:27:28:165 1 11:27:28:165 } 11:27:28:165 protocolIdentifier = { 11:27:28:165 { 11:27:28:165 0 0 8 2250 0 4 } 11:27:28:165 } 11:27:28:165 rasAddress = { 11:27:28:165 ipAddress = { 11:27:28:166 ip = { 11:27:28:166 '0a04102d'H 11:27:28:166 } 11:27:28:166 port = { 11:27:28:167 13030 11:27:28:167 } 11:27:28:167 } 11:27:28:167 } 11:27:28:167 endpointType = { 11:27:28:167 vendor = { 11:27:28:168 vendor = { 11:27:28:168 t35CountryCode = { 11:27:28:168 1 11:27:28:169 } 11:27:28:169 t35Extension = { 11:27:28:169 0 11:27:28:169 } 11:27:28:170 manufacturerCode = { 11:27:28:170 71 11:27:28:170 } 11:27:28:170 } 11:27:28:171 productId = { 11:27:28:171 '6f626a737973'H 11:27:28:171 } 11:27:28:171 versionId = { 11:27:28:172 '76302e382e33'H 11:27:28:172 } 11:27:28:172 } 11:27:28:173 terminal = { 11:27:28:173 } 11:27:28:173 mc = { 11:27:28:173 FALSE 11:27:28:173 } 11:27:28:173 undefinedNode = { 11:27:28:174 FALSE 11:27:28:174 } 11:27:28:174 } 11:27:28:174 endpointAlias = { 11:27:28:174 elem[0] = { 11:27:28:175 h323_ID = { 11:27:28:175 AsteriskVM 11:27:28:175 } 11:27:28:176 } 11:27:28:176 elem[1] = { 11:27:28:176 dialedDigits = { 11:27:28:176 "1200" 11:27:28:176 } 11:27:28:177 } 11:27:28:177 } 11:27:28:177 } 11:27:28:177 } 11:27:28:177 Sent GRQ message 11:27:28:181 GkClient Received RAS Message 11:27:28:181 Received RAS Message = { 11:27:28:181 gatekeeperConfirm = { 11:27:28:181 requestSeqNum = { 11:27:28:181 1 11:27:28:181 } 11:27:28:182 protocolIdentifier = { 11:27:28:182 { 11:27:28:182 0 0 8 2250 0 5 } 11:27:28:182 } 11:27:28:182 rasAddress = { 11:27:28:182 ipAddress = { 11:27:28:182 ip = { 11:27:28:183 '0a04300f'H 11:27:28:183 } 11:27:28:183 port = { 11:27:28:183 1719 11:27:28:184 } 11:27:28:184 } 11:27:28:184 } 11:27:28:184 } 11:27:28:184 } 11:27:28:184 Gatekeeper Confirmed (GCF) message received. 11:27:28:184 ERROR:No Gatekeeper ID present in received GKConfirmed message 11:27:28:184 Ignoring message and will retransmit GRQ after timeout 11:27:28:184 Error: Failed to handle received RAS message 11:28:28:346 Gatekeeper client GRQ timer expired. 11:28:28:346 Error:Gatekeeper could not be found 11:28:28:346 Error: Gatekeeper error.
