Hi Jan, I have downloaded GnuGK FailOver Snapshot from http://www.gnugk.org/failover-snapshot.html and compiled successfully without error .When I am sending call , phone is ringing but not getting ringback tone or Audio after connected . If I make 10 calls then 1/2 call had ringback and Voice as normal but the rest of the calls had "NO AUDIO" . It is happening at NATed endpoint or even from Public IP's endpoint. Here is below my .ini file . # gnugk.ini # ========= [Gatekeeper::Main] Fourtytwo=42 Name=GnuGK TimeToLive=120 [RoutedMode] GKRouted=1 H245Routed=1 CallSignalPort=1721 CallSignalHandlerNumber=2 RtpHandlerNumber=2 RemoveH245AddressOnTunneling=1 DropCallsByReleaseComplete=1 RemoveCallOnDRQ=1 SendReleaseCompleteOnDRQ=1 AcceptNeighborsCalls=1 AcceptUnregisteredCalls=1 SupportNATedEndpoints=1 TcpKeepAlive=1 ConnectTimeout=60000 SetupTimeout=30000 SignalTimeout=30000 ForwardOnFacility=1 ShowForwarderNumber=1 TranslateFacility=1 SocketCleanupTimeout=5000 Q931PortRange=20000-20999 H245PortRange=30000-30999 ActivateFailover=1 FailoverCauses=1-15,21-127 [Proxy] Enable=1 InternalNetwork=10.0.0.0/8,172.16.0.0/12,192.168.0.0/16 T120PortRange=40000-40999 RTPPortRange=50000-59999 ProxyForNAT=1 [CallTable] DefaultCallDurationLimit=7200 IRRFrequency=0 IRRCheck=FALSE SingleFailoverCDR=TRUE [GkStatus::Auth] default=forbid rule=explicit 127.0.0.1=allow KeyFilled=123 Shutdown=disable DelayReject=3 [Gatekeeper::Auth] default=allow [Gatekeeper::Acct] FileAcct=optional;stop [FileAcct] DetailFile=/usr/local/gatekeeper/cdr.log StandardCDRFormat=0 CDRString=Call-%n|IP=%{caller-ip}:%{caller-port}|Pin=%u|Tel=%{Calling-Station-Id}|DialedNo=%{Dialed-Number}|RewrNo=%{Called-Station-Id}|Start=%{connect-time}|Stop=%{disconnect-time}|ConfID=%{ConfId}|SessID=%s|RingTime=%{ring-time} | Duration=%d | TotalDuration=%t | PDD=%p |DisCause=%c| WhoDisc=%r |GW=%{callee-ip}:%{callee-port} | Attempt=%{call-attempts} |LastCDR=%{last-cdr} |CallersRtpIP=%{media-oip} |Codec=%{codec} TimestampFormat=MySQL UseDialedNumber=1 [RasSrv::RRQFeatures] AcceptGatewayPrefixes=1 OverwriteEPOnSameAddress=1 AcceptEndpointIdentifier=1 IRQPollCount=0 [RasSrv::ARQFeatures] CallUnregisteredEndpoints=1 RoundRobinGateways=1 ArjReasonRouteCallToSCN=1 ArjReasonRouteCallToGatekeeper=1 RemoveTrailingChar=# ## For Permanent END Point [RasSrv::PermanentEndpoints] 69.xx.xx.12=TestGW1;02 69.xx.xx.13=TestGW2;02 ## GW Name and Prefixes [RasSrv::GWPrefixes] TestGW1=02 TestGW2=02 ## Call control Per Gateway, 1 = Highest Priority [EP::TestGW1] Capacity=2 GatewayPriority=1 [EP::TestGW2] Capacity=3 GatewayPriority=2 ;;;;; gnugk.ini EOF ;;;;;; Note : With the same ini file gnugk-v.2.3.3 or gnugk-v.2.2.2 working fine .
