openh323gk-users Thank you for your answer ! But I still failed ! I set the new inis ,as follows: ;####################################### # Gatekeeper 1 configuration (parent) ;####################################### [Gatekeeper::Main] Fourtytwo=42 Name=GK1 Home=192.168.0.28 TimeToLive=600 [RoutedMode] GKRouted=1 H245Routed=0 CallSignalPort=1721 AcceptNeighborsCalls=1 [GkStatus::Auth] rule=allow ;####################################### # Gatekeeper 2 configuration (child) ;####################################### [Gatekeeper::Main] Fourtytwo=42 Name=GK2 Home=192.168.0.28 TimeToLive=600 UnicastRasPort=51719 EndpointSignalPort=1820 StatusPort=8000 [RoutedMode] GKRouted=1 H245Routed=0 CallSignalPort=51721 AcceptNeighborsCalls=1 [Endpoint] Gatekeeper=192.168.0.28:1719 Type=Gateway H323ID=GK2 E164=188600 Prefix=1886 TimeToLive=900 RRQRetryInterval=10 [Endpoint::RewriteE164] 1886=6 [GkStatus::Auth] rule=allow ;; GK1 ;; / \ ;; / \ ;; / \ ;; / \ ;; GK2 ;; Prefix=1886 188200 ;; \ ;; \ ;; \ ;; 601 ;; I can 188200 call 601 by 188601, and call 602 by 188602; but I cannot 601 call 188200,when 601 call 188200,I can see : 601 call with 188200 completed , but 188200 is still waiting ! It is why? And how can I set parent gatekeeper and child inis? logs: 2004/09/30 09:55:35.553 4 ProxyChannel.cxx(1151) GWRewrite source: call record 2004/09/30 09:55:35.553 2 ProxyChannel.cxx(1193) Q931 Warning: a registered call from my GK(192.168.0.28:1937) 2004/09/30 09:55:35.553 2 gkacct.cxx(936) GKACCT Successfully logged event 1 for call no. 1 2004/09/30 09:55:35.553 2 RasTbl.cxx(1904) CDR ignore not connected call 2004/09/30 09:55:35.553 2 gkacct.cxx(936) GKACCT Successfully logged event 2 for call no. 1 2004/09/30 09:55:35.553 3 RasSrv.cxx(203) RAS Send to 192.168.0.28:1719 disengageRequest { requestSeqNum = 4 endpointIdentifier = 9 characters { 0038 0032 0039 0033 005f 0065 006e 0064 8293_end 0070 p } conferenceID = 16 octets { 8c 2a a1 09 2a f1 18 10 88 ad 00 e0 4c 39 83 14 .*..*.......L9.. } callReferenceValue = 24203 disengageReason = normalDrop <<null>> callIdentifier = { guid = 16 octets { 8c 2a a1 09 2a f1 18 10 88 ac 00 e0 4c 39 83 14 .*..*.......L9.. } } gatekeeperIdentifier = 3 characters { 0047 004b 0031 GK1 } answeredCall = FALSE wubo wubo@xxxxxxxxxxx 2004-09-21 ???????????????????????甸?X?????!3搿????!3??h汗?K!:k≯?颧????,????r㈦a?(~??⒔氍b?:??禳g??N?g?h?'?'??仇??▲??????楫?r??????韬冠?(?.?┊????????????????????????+-?^?鲛 ?谦躇b槽??q玷????b斤岫??(悍~?{?幅?V??麒??????z&z?{???0??O?
