[Serusers] portaone RTP proxy problems

Happy new year everyone!! first of all, I'd like to thank those who answered my questions last time. now I've got a question with Portaone RTP prozy (which recommended in the voip-info.org web site. I downloaded the tar ball and compile the source code. I executed the command ./rtpproxy and saw it running by "ps" it. Now when I typed "ser -E" on my console, I've got the following errors. [root@localhost ser]# ser -E 0(6085) WARNING: could not rev. resolve 192.168.1.101 Listening on 127.0.0.1 [127.0.0.1]:5060 192.168.1.101 [192.168.1.101]:5060 Aliases: localhost:5060 localhost.localdomain:5060 stateless - initializing Maxfwd module- initializing 0(6087) mod_init(): Database connection opened successfuly exec - initializing print - initializing textops - initializing 0(0) INFO: udp_init: SO_RCVBUF is initially 65535 0(0) INFO: udp_init: SO_RCVBUF is finally 131070 0(0) INFO: udp_init: SO_RCVBUF is initially 65535 0(0) INFO: udp_init: SO_RCVBUF is finally 131070 [root@localhost ser]# 1(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 1(0) WARNING: rtpp_test: can't get version of the RTP proxy 1(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 2(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 2(0) WARNING: rtpp_test: can't get version of the RTP proxy 2(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 3(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 3(0) WARNING: rtpp_test: can't get version of the RTP proxy 3(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 4(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 4(0) WARNING: rtpp_test: can't get version of the RTP proxy 4(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 5(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 5(0) WARNING: rtpp_test: can't get version of the RTP proxy 5(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 6(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 6(0) WARNING: rtpp_test: can't get version of the RTP proxy 6(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 7(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 7(0) WARNING: rtpp_test: can't get version of the RTP proxy 7(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 8(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 8(0) WARNING: rtpp_test: can't get version of the RTP proxy 8(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 9(0) INFO: fifo process starting: 6130 9(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 9(0) WARNING: rtpp_test: can't get version of the RTP proxy 9(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 10(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 10(0) WARNING: rtpp_test: can't get version of the RTP proxy 10(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 11(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 11(0) WARNING: rtpp_test: can't get version of the RTP proxy 11(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 9(6130) SER: open_uac_fifo: fifo server up at /tmp/ser_fifo... 12(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 12(0) WARNING: rtpp_test: can't get version of the RTP proxy 12(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 13(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 13(0) WARNING: rtpp_test: can't get version of the RTP proxy 13(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 14(0) ERROR: send_rtpp_command: can't read reply from a RTP proxy 14(0) WARNING: rtpp_test: can't get version of the RTP proxy 14(0) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 0(6087) ERROR: send_rtpp_command: can't read reply from a RTP proxy 0(6087) WARNING: rtpp_test: can't get version of the RTP proxy 0(6087) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily 15(6161) ERROR: send_rtpp_command: can't read reply from a RTP proxy 15(6161) WARNING: rtpp_test: can't get version of the RTP proxy 15(6161) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily That was asked back to December 8 but there seemed no answer to that question.

RE: [Serusers] Ser, Cisco and NAT

I've never used a 5300 but if I had a guess it would be that the 5300 doesn't realize that the RTP is NAT'd (and should send to a proxy). In other words it may not be sending to your rtpproxy correctly if at all? Do a debug on all devices, ensure the RTP ports match up. Does rtpproxy report any errors such as no payload? You can do an 'rtpproxy -f' to run it at command line. Looking at your config you have a lot of stuff being done before you relay to the 5300, not to mention you have 'forward' under your t_relay..?? Have you tried just sending to route(1) ?? That's where all your 'if natted' statements should be. That way on_reply gets caught correctly as well. ie: if ( uri=~"^sip:9[0-9]*@5300_IP" ) { log(1, "SER22: matched - forward to GW\n"); rewritehostport ("5300_IP:5060"); route(1) break; }; -----Original Message----- From: Victor Chan [mailto:vchan67@hotmail.com] Sent: Wednesday, December 29, 2004 8:11 PM To: serusers(a)lists.iptel.org Subject: [Serusers] Ser, Cisco and NAT I have some problem about Cisco and NAT device.

[Serusers] serctl + authentication failures (update)
by Gurol Akman 31 Dec '04

31 Dec '04

recently i had reported 2 problems. while waiting to hear from the list, i ran some experiments as follows: first, i switched from ser-0.9.0 to ser-0.8.14. i then re-initialized the ser database. afterwards, i was able to do a 'serctl add ..." successfuly. also, i'm now able to authenticate my registration requests. so both problems seem be gone ;-) i'd like to understand one thing better however: how does the information in subscriber database get to be used during the authentication process? stated in other words, which fields of the subscriber table get to be used during authentication? thanks & regards - ga

[Serusers] serctl failure + authentication
by Gurol Akman 30 Dec '04

30 Dec '04

folks i'd appreciate if i could get some pointers re: following incidences... 1. my attempts to invoke serctl to add a new subscriber fail [error: 400; check if you use aliases in SER] at all times which suggest i must be doing something wrong. 2. when i enable the authentication code block in ser.cfg, my 1st registration attempt fails with a response type of 401 (unauthorized) which contains a WWW-Authenticate header. subsequently, my ua (x-lite softphone) sends another register message which contains an Authorization header with some number of credentials. unfortunately, this 2nd attempt also results in a 401 response. are there certain things that i should do on the client/server side to get ser authentication to work? thanks for your help in advance, gurol

Hello, First of all excuse my newbieness. I have just installed SER in a public IP. I read Dan Austin's howto, and understood that I would be able to register using the default configuration file.

[Serusers] Digest Authentication
by Magnus Sörman (AL/EAB) 30 Dec '04

30 Dec '04

Hi, I need some help with digest authentication. When I uncomment those lines in ser.cfg, the register msg stops to work. In the trace, see below, you can see the nonce being sent in the re-register msg, but the server still responds with 401 Unauthorized. I've tried with both 0 and 1 in the www_challenge. Without the digest authentication the register works fine. Thanks in advance, //Magnus ser.cfg (ser 0.8.12 running on a Fedora box.

[Serusers] CDR Issues
by Adrian Georgescu 30 Dec '04

30 Dec '04

Erik, CDRTool guarantees 100% accurate accounting for call detail records generated by SIP Express Router in combination with MediaProxy regardless of the presence of BYE messages. This solution is available under commercial agreement. http://www.ag-projects.com/CDRTool.html Regards, Adrian >>>>>>>>>>>> OK, i've run into a problem with the CDR Creation. If you have 2 users who call each other, talk a while and then instead of hanging up decide to pull the plugs from their phones (or terminitate their application), no complete CDR is generated, the INVITE and ACK are logged, but since no one realy hangs up there won't be a BYE record, so no CDR end/total time and no billable time. Use the / a rtpproxy you would say, to bad it suffers from the same problem, if both partes put the call on hold and pull the plug the call keeps existing and once again an incomplete CDR. Has anyone ever suffered the same problem? And what is the most reliable way to generate CDRs? Kind regards, E. Versaevel
