I think the sip-implementors sip-implementors(a)cs.columbia.edu or sip sip(a)ietf.org mailinglist could help you more. Klaus -----Original Message----- From: Chuck Ramirez [mailto:chuck_ramirez@yahoo.com] Sent: Wednesday, December 10, 2003 8:34 PM To: serusers(a)lists.iptel.org Cc: Klaus Darilion Subject: Xlite register problem (WAS Xten-RTPProxy choppy audio) Hi, We are also having a problem with X-Pro and X-lite build 1088 when registering to a SIP proxy based on libosip. The X-Pro is not using the double-quotes on the nonce value of the Authorization header, which is causing an error on our proxy when parsing of this header (Libosip requires the double quotes). I have sent this question to the Xten support forum but they said that the double quotes are not mandatory, though libosip requires them. Any thoughts on what is the correct behaviour of the double-quotes on the authorization header? Thanks, Chuck ######## REGISTER sip:sip.myproxy.com SIP/2.0..

[Serusers] another RTPProxy for SER
by Adrian Georgescu 10 Dec '03

10 Dec '03

Hello, we have released an alternative RTPProxy that works with SER nathelper module. Is a completely new program written in Python and should be able to run without recompilation on any system where Python is supported. We have tested Linux Debian and Solaris 8. There are little differences against PortaOne's rtpproxy, mainly the problem with Xten choppy audio was solved. Features - Compliant with SER nathelper module - Runs without recompilation on SUN Solaris - Xten audio quality is perfect without gaps - Display active media sessions - Display traffic in minutes and kilobytes - Log to syslog the IP/port numbers and traffic statistics per session - Flexible design for adding new features To do list - Run it on separate machine than SER - Log network traffic per domain - Integrate traffic logging with CDRtool The application is free to download and use without limitations. You can download it from: http://download.dns-hosting.info/RTPProxy/ The application is developed and supported by AG Projects. Any feedback is welcome at support(a)jobserver.org Regards, Adrian Georgescu ag(a)ag-projects.com http://ag-projects.com Tel: +31-23-5458104 IP phone: sip:ag@ag-projects.com ------------------------------------------------ DNS, ENUM & IP telephony http://managed-dns.org/

Sending to rtp port +1 is ok, that is RTCP. the RTCP port is defined as rtp+1. better would be if the RTP proxy would also forward RTCP, nevertheless x-lite should also handle clients which do not support RTCP (and answers with ICMP errors).

Ethereal also can do all the analysis: mark an UDP (RTP) packet, right-click, decode as ... select RTP. Then mark the RTP packet, ->Tools->Statistics->RTP stream->Analyse. There you will see a list of all RTP packets with jitter/packet loss analysis. Furthermore you can save the payload to disc and listen to it. What causes the choppy audio - packet loss or jitter? Is the problem caused by using X-lite as sender or receiver?

Not able to register. I have given proxy ip : iptel.org and port : 5060 What values should be given in outbound proxy and port Enable NAT : yes My phone is working behind firewall & NAT. Whether the nathelper module is enabled by iptel.org by default..? Or I have to take care of the messages with NAT modifications..? I can send and receive messages on the same port. Kindly Help..
