[OpenSER-Users] SCTP support
by Daniel-Constantin Mierla 03 Aug '07

03 Aug '07

Hello, courtesy of Glenn Marmon, Connecticut College Class of 2007, who submitted the patch, OpenSER includes now support for SCTP (Stream Control Transmission Protocol). It completes the list of the possible IP transport layers that could be used with SIP in OpenSER. You can find details about SCTP at: http://www.sctp.org/ Basically, it is a reliable transport protocol, like TCP, but provides a number of functions that are critical for telephony signaling transport (read more about the benefits: http://www.ietf.org/rfc/rfc3286.txt). If you have the chance to own a SCTP-aware SIP phone and can test, please provide us feedback on the mailing lists -- also, let us know the name and type of any SIP phone with SCTP support that you know. Hope SCTP will gain more and more space, as it seems to be the right protocol for VoIP/IM&P signaling, where UDP cannot cope very well with huge messages and TCP adds too much overhead. Cheers, Daniel

[OpenSER-Users] Logs to /var/log/openser
by Iñaki Baz Castillo 03 Aug '07

03 Aug '07

Hi, I've configured: log_facility=LOG_LOCAL0 and added in "syslog.conf": # don't log messages with LOG_LOCAL0 in /var/log/syslog anymore *.*;auth,authpriv.none,local0.none -/var/log/syslog # # log messages with LOG_LOCAL0 in /var/log/ser.log local0.* -/var/log/ser.log as it appears in http://docs.huihoo.com/openser/tutorials/ser-syslog/ar01s06.html OpenSer then logs in /var/log/openser, true, but it still logs in /var/log/syslog. ¿?¿ Obviously I don't want OpenSer logs appearing in /var/log/syslog. I use Debian Etch, any idea of what can be wrong? Thanks a lot. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[OpenSER-Users] avp_subst and regex
by Zahid Mehmood 02 Aug '07

02 Aug '07

Hi, I am trying to rewrite a 5 digit number to a 11 digit number by adding a prefix "121285". To achieve that I use the following: avp_subst("$avp(s:fromuri)","/^(sip:)([134][0-9]{4}@.*)/\1+121285\2/"); in openser.log new fromuri = sip:+12128512345@host.columbia.edu It works fine because of the "+" after \1 This avp_subst does not work properly if the "+" is taken out. How can I use "\1" followed by another digit? avp_subst("$avp(s:fromuri)","/^(sip:)([134][0-9]{4}@.*)/\1121285\2/"); in openser.log: new fromuri = J128512345(a)host.columbia.edu What am i doing wrong? Thanks in advance for your help. -- Zahid

[OpenSER-Users] OpenSER looping routes back to itself.
by Taylor Carpenter 02 Aug '07

02 Aug '07

Running OpenSER v1.1.1 with internal ip for sip client connections and ext ip to connect to sip providers. I am getting loops in my calls sometimes... They stop after reaching the max hops trying to send the BYE message to it self. I am wondering if it is the record- route that I see that includes the internal IP. The 483 error is U 2007/07/30 00:49:56.133157 192.168.18.22:5060 -> 192.168.18.22:5060 SIP/2.0 483 Too Many Hops. From: <sip:15126461516@192.168.18.1:5060>;tag=nu-481d-6c62.

[OpenSER-Users] benchmark module
by Daniel-Constantin Mierla 02 Aug '07

02 Aug '07

Hello, starting from the original patch submitted by Bastian Friedrich and incorporating the code used in the core for past benchmarking, the devel version has a new module "benchmark". It can be used to log the duration of a configuration part execution, allowing in this way to detect slow elements of routing script. I am sure is a important tool, at least in preparing production systems, so development will continue to make more flexible the printed statistics. The readme file will give you more details: http://www.openser.org/docs/modules/1.3.x/benchmark.html The module exports an internal API, so developers can do benchmarking inside the C code. Feedback is appreciated. Cheers, Daniel

[OpenSER-Users] Replacing "." of a domain with "_" and store the result in a variable
by Iñaki Baz Castillo 02 Aug '07

02 Aug '07

Hi, I just need to take the requested domain $rd and store in a variable that domain but with . replaced by _: sip.domain.org -> sip_domain_org This is because I want tables in MySQL containing the domain name but MySQL don't allow . in table name. So now, what should I do for that? I really thought "textops" could help me but I don't see a function to replace text and store it in a variable. I see "replace()" and "subst()" but they seem to exist for replacing text in the SIP message "on the fly", that is not that I'm looking for. Any suggestion? Thanks a lot. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[OpenSER-Users] openser to solve SIP+RTP+NAT problems in typical SOHO setup
by Jens Thiele 02 Aug '07

02 Aug '07

Hi, I am evaluating software to solve SIP+RTP+NAT problems in typical SOHO setups: Scenarios: Typical scenarios are (A)DSL "dial-up / dynamic IP" connections with one public IP and a router doing NAT for some LANs. 1) WAN multiple LANs internet <-> NAT router <-> SIP phones sip registrar SIP proxy <-> SIP phones with NAT logic : 2) WAN multiple LANs internet <-> NAT router <-> SIP proxy with NAT logic, SIP phones sip registrar <-> SIP phones : Notes: - the SIP phones use the SIP proxy with NAT logic as outbound proxy - the proxy is notified if the public IP changes The closest match so far has been siproxd [1]. But I would prefer to use openser+nathelper+rtpproxy. Now it seems nathelper is designed for a different scenario (SIP provider): WAN/internet sip registrar <-> ser+nathelper <-> NAT router <-> multiple LANs with SIP phones and uses the packet source address in fix_nated_contact. Now I stumbled across milkfish [2] and its patches [3] to openser (nathelper). It seems the patch allows to explicitly set the address used by fix_nated_contact to rewrite the contact header (instead of using the packet source address). Searching the mailing list archives I did not find a better solution. Closest match I found was the thread: "[Devel] Extended nathelper" started by Walter Schober http://www.mail-archive.com/devel@openser.org/msg01930.html Ending in the suggestion to use add_rvc_param(). But add_rcv_param seems to use the packet source address, too. But also from this thread it seems one might use the mangle module to rewrite the contact header field, but then I am not sure about the state of this module: "This is a module to help with SDP mangling. Still in testing." I am a bit surprised that there is no straight forward solution to such a common setup. Am I missing something really obvious? Thanks Greetings Jens Thiele [1] siproxd <http://siproxd.sourceforge.net/> [2] milkfish <http://wiki.milkfish.org> [3] milkfish openser patches <http://packages.milkfish.org/boozy/Milkfish_Sources_for_OpenWrt-SDK/OpenWrt…>
