First: what do you mean by "supporting RFC 3841" ... can't you script it? Secondly: whether as scripting or not, my individual plans are not as important as whether there is some individual on this mailing list willing to do it, there is really not a grand plan.... I think the most reasonable next step would be for someone desiring to have it to script it and share it. >This is sad because 3GPP's CSCFs require these headers, and the >OpenIMSCore project uses SER to implement its CSCFs.

[OpenSER-Users] sanitizing sip requests

by William Quan

Hi all, I came across a security alert that basically embeds javascript in the display name of the From to initiate cross-site-scripting (XSS) attacks. Here is an example: From: "<script>alert('hack')</script>""user" <sip:user at domain.com <https://lists.grok.org.uk/mailman/listinfo/full-disclosure>>;tag=002a000c Grammatically , I don't see an issue with this. However, under the right circumstances this could get ugly. Do you see value in having openser take a proactive role to detect these and reject calls? Or is this outside the scope of what a proxy should be doing (leave it to the UA to sanitize) ? Looking to get your thoughts- -will

[OpenSER-Users] OpenSER SIP registrar - third party registration

by Pascal Maugeri

Hi I would like to make OpenSER SIP REGISTRAR to advertise my SIP server that a user just registered successfully to the domain. My server has to make a call to this user as soon as he's registered. First of all is this called "third party registration" ? In practice how does it work ? OpenSER sends a REGISTER to my server and my server replies with 200 OK ? Which script command should I use ? Thanks in advance for your help Pascal

[OpenSER-Users] question regarding record-route and via

by vallimamod abdullah

Hello list, I am trying to understand why the thomson ST2030 hard phone does not work with my openser. I have noticed while ngreping that it seems to not respect the record-route header. I have the following incoming invite: U 2007/10/18 19:31:54.067545 xx.xx.33.119:5060 -> 10.0.0.136:15060 INVITE sip:1920@10.0.0.136:15060;user=phone SIP/2.0. Record-Route: <sip:xx.xx.33.119:5060;nat=yes;lr=on>. Via: SIP/2.0/UDP 192.168.5.119;branch=z9hG4bKae88.af6caa.0. Via: SIP/2.0/UDP 192.168.5.120:5060;branch=z9hG4bK58e93388;rport=5060. From: <sip:6897@192.168.5.120>;tag=as246d1f36. To: <sip:1920@192.168.5.119>. And the phone answers to the IP of the first via instead of the one in record-route: U 2007/10/18 19:31:54.083370 10.0.0.136:15060 -> 192.168.5.119:5060 SIP/2.0 100 Trying. Via: SIP/2.0/UDP 192.168.5.119;branch=z9hG4bKae88.af6caa.0. Via: SIP/2.0/UDP 192.168.5.120:5060;branch=z9hG4bK58e93388;rport=5060. From: <sip:6897@192.168.5.120>;tag=as246d1f36. To: <sip:1920@192.168.5.119>. I would like to know the opinion of SIP gourous out there: is this rfc-compliant ? I don't have this issue with other phones so I am wondering if I should ask for a refund... Thank you ! -- Regards, - vma .

Re: [Serusers] RFC 3841 support?

by Jiri Kuthan

There is no explicit support for callerprefs. I think though that most of the scenarios they are goof for could be achieved using textops and selects+AVP processing. -jiri At 15:40 18/10/2007, Stefan.Brozinski(a)materna.de wrote: >Hello everybody > >are there any plans to support RFC 3841 in SER? > >Specifically, I am looking at the 'Accept-Contact' and the >'Request-Disposition' header fields. > >Thanks >Stefan >_______________________________________________ >Serusers mailing list >Serusers(a)lists.iptel.org >http://lists.iptel.org/mailman/listinfo/serusers -- Jiri Kuthan http://iptel.org/~jiri/

[Serusers] Documentation search problem

It just came to my attention that some pages on iptel.org do not function properly, including the doc search tool. While we try to rectify the problem, here's an alternative link: http://siprouter.onsip.org/doc/docsearch/ g-)

Re: [Serusers] Get RealTime Online Users status

by roayu

Hi Jiri! I've captured and analyzed those SIP message dumps. I found that when Sjphone A sent a NOTIFY signal to the SER (after Sjphone A accepted the REFER), SER didn't pass the NOTIFY to the SPA942 to terminate the call between them. Therefore, Sjphone A unable to INVITE Sjphone B to bridge up the connection. May I know what causes this? Thanks for your precious time and reply!

[Serusers] RTPProxy question

by Mitya

Hi all, I have a few unclarified questions in my head about RTPProxy. I think I know the basic concept, but I'm curious to know a few details. How does the proxy transfer the packets from A to B ? When it gets a packet from A, does it send it immediately to B (when its possible) without any delay or timing ? Or does it have a buffer (few ms buffer), where it re-orders the packets ? Does it parse the RTP stream ? Does it generate RTCP packets ? Can somebody help me in this ? Thanks, Mitya

[OpenSER-Users] "200 OK" not SDP fixed by RtpProxy... but it works ! ¿?

by Iñaki Baz Castillo

Hi, user_A with STUN calls to user_B behind NAT with no STUN. onreply_route[1] { if (nat_uac_test("1")) fix_nated_contact(); if (isbflagset(6) && status=~"(180)|(183)|2[0-9][0-9]") force_rtp_proxy("l"); } In the initial request bflag(6) is up because "location" of user_B so RtpProxy is used in the INVITE and 200-OK. But in re-INVITE bflag(6) is down and is not applied force_rtp_proxy("l"); in the 200-OK. In fact I debug the SIP trace in the re-INVITE in OpenSer: ---------------------------------------------------------------------- # user_A -> OpenSer INVITE sip:user_B@112.121.235.28:5061 SIP/2.0 c=IN IP4 212.121.235.18 # OpenSer -> user_B INVITE sip:806@212.121.235.18:5061 SIP/2.0 c=IN IP4 80.94.0.110 <---- RtpProxy applied (OK) # user_B -> OpenSer SIP/2.0 200 OK c=IN IP4 192.168.1.106 [*1] *1: Needs RtpProxy but bflag(6) is down so not applied. # OpenSer -> user_A SIP/2.0 200 OK c=IN IP4 192.168.1.106 <-- RtpProxy NO applied ---------------------------------------------------------------------- But I can confirm that the audio works after re-INVITE in both directions!!! ¿? I've debugged with tcpdump, the RTP is send to RtpProxy from user_A, how is possible?? Thanks. -- Iñaki Baz Castillo ibc(a)in.ilimit.es
