Chrischevy Posted May 27, 2010 Report Share Posted May 27, 2010 Hi everyone, this is my first post here. We're in a rush to find a new phone system for our multisites company. First, we want to make sure our current faxes machines will work with pbxnsip. We have a couple of Ricoh machine (C2550 and 171) with integrated sip support. Here are my options in the Ricoh's interface (bold means selected): Enable SIP: On/Off Enable Server: On/Off Username: (I tried the extension and admin) Server IP Address: 10.x.x.x (our pbxnsip address) Digest Authentication: On/Off (I've tried to turn this on and use a password) On the pbxnsip side, I simply created an extension (99) and assigned it's MAC address (Bind to MAC Address:) under registration. I have tried registering the Ricoh machine with and without password, rebooting between each try, still I can't register the extension... Am I missing a step ? I registered 2 phones without any problems, (I had to enter a sip-password and id from the phone.) Thanks in advance for your help ! Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted May 29, 2010 Report Share Posted May 29, 2010 Believe it or not, we have the same device in the office. I noticed the SIP/H.323 features and was wondering what this would be good for? Now I know. Can't wait to get back to the office... Quote Link to comment Share on other sites More sharing options...
Chrischevy Posted May 31, 2010 Author Report Share Posted May 31, 2010 Now both of our Ricoh Fax machines can register with the pbxnsip server (we had to use blank password), but when I try to send / receive a fax between them (not going through any trunk), it does not work. In the log, I can clearly see that both devices are negotiating the connection, switching to t38 and then the sending machine sends an ACK, but the receiving machine never responds. Sending machine retry the ACK, still receives no answer and then drop the connection. Any advice? Here's a copy of the log file: [7] 2010/05/31 14:22:38: SIP Tx udp:192.168.7.10:5060: SIP/2.0 100 Trying Via: SIP/2.0/UDP 192.168.7.10;branch=z9hG4bKB'i8lXA_3T1Vn From: "Fax PBrunet23" <sip:98@pbx.company.com>;tag=QQL7De5Q+L To: "Fax PBrunet24" <sip:99@pbx.company.com>;tag=42226 Call-ID: 497f14cf@pbx CSeq: 1 INVITE Content-Length: 0 [7] 2010/05/31 14:22:38: SIP Rx udp:10.0.0.23:65378: ACK sip:99@10.0.0.66;user=phone SIP/2.0 Via: SIP/2.0/UDP 10.0.0.23;branch=z9hG4bK!1r!Cm+YdarSp Max-Forwards: 70 From: <sip:99@10.0.0.23;user=phone>;tag=p05H4*cJDI To: <sip:98@10.0.0.66;user=phone>;tag=4fc4fc1483 Call-ID: 20100531142239-T38-C-RytBI@10.0.0.23 CSeq: 1 ACK Content-Length: 0 [7] 2010/05/31 14:22:39: SIP Rx udp:10.0.0.23:65378: ACK sip:99@10.0.0.66;user=phone SIP/2.0 Via: SIP/2.0/UDP 10.0.0.23;branch=z9hG4bKWkkancr4UpW5G Max-Forwards: 70 From: <sip:99@10.0.0.23;user=phone>;tag=p05H4*cJDI To: <sip:98@10.0.0.66;user=phone>;tag=4fc4fc1483 Call-ID: 20100531142239-T38-C-RytBI@10.0.0.23 CSeq: 1 ACK Content-Length: 0 [5] 2010/05/31 14:23:10: Did not receive ACK, disconnecting call 497f14cf@pbx Thanks!

In the meantime, can you attach the whole trace? Maybe then we can see where the problem is... Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted June 2, 2010 Report Share Posted June 2, 2010 We can reproduce the problem now... Seems like the sending T.38 over TCP screws things up. We'll see how we can get this working. Quote Link to comment Share on other sites More sharing options...
