I have setup asterisk on one system and gnugk on another. I can make calls between the H.323 endpoints (netmeeting and cisco 7905) and can call from an H.323 endpoint to an asterisk extension and out onto the PSTN. When I try to call from asterisk to an H.323 device the call is dropped immediately following a brief exchange between the two servers. gnugk seems to recognise the call and the details seem ok, but it just gets rejected. I suspect that as the call is being rejected so quickly that it must be something basic, but I can't see it. Anyone come across this before? many thanks in advance, Brian. -- logs from an attempted call from 4001 (asterisk) to 3105 (gnugk) Asterisk h323 trace 31:31.087 ThreadID=0x4ed75b30 H323 Making call to: 3105@xxxxxxxxxxxxxx 31:31.088 ThreadID=0x4ed75b30 H323 Added capability: G.711-ALaw-64k{hw} <1> 31:31.088 ThreadID=0x4ed75b30 H323 Added capability: G.711-uLaw-64k{hw} <2> 31:31.088 ThreadID=0x4ed75b30 H323 Added capability: G.729{hw} <3> 31:31.088 ThreadID=0x4ed75b30 H323 Added capability: UserInput/hookflash <4> 31:31.088 ThreadID=0x4ed75b30 H323 Added capability: UserInput/basicString <5> 31:31.088 ThreadID=0x4ed75b30 H323 Added capability: UserInput/dtmf <6> 31:31.088 ThreadID=0x4ed75b30 H323 Added capability: UserInput/RFC2833 <7> 31:31.088 ThreadID=0x4ed75b30 H323 FindCapability: 1 31:31.089 ThreadID=0x4ed75b30 H323 Found capability: G.711-ALaw-64k{hw} <1> 31:31.089 ThreadID=0x4ed75b30 H323 FindCapability: 2 31:31.089 ThreadID=0x4ed75b30 H323 Found capability: G.711-uLaw-64k{hw} <2> 31:31.089 ThreadID=0x4ed75b30 H323 FindCapability: 3 31:31.089 ThreadID=0x4ed75b30 H323 Found capability: G.729{hw} <3> 31:31.089 ThreadID=0x4ed75b30 H323 FindCapability: 4 31:31.089 ThreadID=0x4ed75b30 H323 Found capability: UserInput/hookflash <4> 31:31.089 ThreadID=0x4ed75b30 H323 FindCapability: 5 31:31.089 ThreadID=0x4ed75b30 H323 Found capability: UserInput/basicString <5> 31:31.089 ThreadID=0x4ed75b30 H323 FindCapability: 6 31:31.089 ThreadID=0x4ed75b30 H323 Found capability: UserInput/dtmf <6> 31:31.089 ThreadID=0x4ed75b30 H323 FindCapability: 7 31:31.089 ThreadID=0x4ed75b30 H323 Found capability: UserInput/RFC2833 <7> 31:31.089 ThreadID=0x4ed75b30 RFC2833 Handler created 31:31.089 ThreadID=0x4ed75b30 H323 Added capability: G.729{hw} <1> 31:31.090 ThreadID=0x4ed75b30 H323 Created new connection: ip$localhost/27117 31:31.090 H225 Caller:8166918 H225 Started call thread 31:31.094 H225 Caller:8166918 Trans Making request: admissionRequest 31:31.094 H225 Caller:8166918 Trans Sending PDU: 31:31.094 H225 Caller:8166918 Trans Waiting on response to seqnum=5890 for 3.0 seconds 31:31.106 Transactor:81583f0 H225RAS Receiving PDU: 31:31.106 Transactor:81583f0 Trans Using credentials from request: H235AnnexD_Procedure1<no-pwd>,MD5<no-pwd>,CAT<no-pwd> 31:31.107 H225 Caller:8166918 H323 Bandwidth used: 0 31:31.108 H225 Caller:8166918 H323TCP Connecting to 195.206.197.59:1720 (local port=10006) 31:31.108 H225 Caller:8166918 H323TCP Could not connect to 195.206.197.59:1720 (local port=10006) - Connection refused(111) 31:31.109 H225 Caller:8166918 H323 Clearing connection ip$localhost/27117 reason=EndedByNoEndPoint 31:31.109 H225 Caller:8166918 H323 Call end reason for ip$localhost/27117 set to EndedByNoEndPoint 31:31.109 H225 Caller:8166918 H225 Sending release complete PDU: callRef=27117 31:31.110 H225 Caller:8166918 H323 Clearing connection ip$localhost/27117 reason=EndedByTransportFail 31:31.111 H323 Cleaner H323 Cleaning up connections 31:31.111 H323 Cleaner H323 Connection ip$localhost/27117 closing: connectionState=NoConnectionActive 31:31.111 H323 Cleaner H323 H323Transport::Close 31:31.111 H323 Cleaner H323 H323Transport::CleanUpOnTermination for H225 Caller:8166918 31:31.112 H323 Cleaner Trans Making request: disengageRequest 31:31.112 H323 Cleaner Trans Sending PDU: 31:31.113 H323 Cleaner Trans Waiting on response to seqnum=5891 for 3.0 seconds 31:31.120 Transactor:81583f0 H225RAS Receiving PDU: 31:31.120 Transactor:81583f0 Trans Using credentials from request: H235AnnexD_Procedure1<no-pwd>,MD5<no-pwd>,CAT<no-pwd> 31:31.120 H323 Cleaner H323 Connection ip$localhost/27117 terminated. 31:31.121 H323 Cleaner H323 Connection ip$localhost/27117 deleted. 31:31.122 H323 Cleaner H323 Cleaning up connections 31:31.201 ClearCallT...d:0815b288 H323 Attempt to clear unknown call ip$localhost/27117 GNU output ?
