[Serusers] exec module question
by Andres 28 Oct '03

28 Oct '03

Hi, I am testing the exec module by outputting some variables to a flat file using: SIP_HF_<hf_name> So for example I put something like exec_msg("echo `date` - From: $SIP_HF_FROM To: $SIP_HF_TO Contact: $SIP_HF_CONTACT Src_IP: $SIP_SRCIP User-Agent: $SIP_HF_USER-AGENT >> /var/log/ser/ser_register.log"); but the User-Agent header field does not get passed even though a sniffer trace shows it in the SIP REGISTER request. Can somebody tell me why not? Thanks, Andres

[Serusers] Support for offline messages in an IM conference
by Madhuri garigipati 28 Oct '03

28 Oct '03

Hello All, I was going through the msilo package in SER modules. It says - "It stores received messages for an offline user and sends them when the user becomes online." I am creating a J2ME IM client for mobile devices using SIP at the backend. And the problem with mobile devices is connection loss. So I am planning to provide a feature to my IM client where in if more than 2 users are in a conference chat room, and one user gets disconnected for some reason, I want to store the messages during the user's absense and send it back to the user when they reconnect. Is this possible with SIP and SER? Does SER module msilo or any other module support offline messages for a conference chat? Thanks, Madhuri. --------------------------------- Do you Yahoo!?

[Serusers] Messenger5.0 481 Error continued
by Rork, Joseph (J.P.) 28 Oct '03

28 Oct '03

I've followed the instructions: Attention: instant messaging model has changed from 4.7 to 5.0 dramatically and in a non-standard way. 5.0 takes session establishement using INVITE and drops out-of-dialog MESSAGEs on the floor, whereas sending "481 Call Leg/Transaction...". To permit them, apply the following registry setting: HighSecurityMode HKLM\Software\Policies\Microsoft\Messenger\Client\{83D4679F-B6D7-11D2-BF36-0 0C04FB90A03}\_Default\EnableSIPHighSecurityMode DWORD= 0 -- Low Security 1 -- High Security 2(Default, same as not set) --- Medium security You need set it to 0 in order to make peer-to-peer IM. Since WM4.7 client is not registered in the LCS server, I guess that WM5 treats it as peer-to-peer call. And I'm still getting the following error: <<messenger5dump>> Any ideas? --joe

Re: [Serusers] SER Contact rewrite for Softswitch
by Jiri Kuthan 28 Oct '03

28 Oct '03

If you need to achieve security, why don't you let the proxy server authenticate callers using digest identity and the gateway trust the proxy by ip address? That's the most common practice today, we use it with our Cisco gateway too. -jiri At 04:27 PM 10/23/2003, Harry Behrens wrote: >Hello, > >we have the following setup in our "Unified Messaging lab": > >SUAs <-> LAN <-> SER <-> Softswitch <-> PSTN > >The SER is provisioned as a SIP Server (essentially a SUA) from the Softswich point of view. > >We have provisioned a number block of 20 numbers (from a 30-channel ISDN PRI) for direct inward dialling (DID) to the SER. >E.g. 12345620-12345639 are routed to the SER. > >On the SER we have a number of users <user>@dai-labor.de, where the first 20 users have an alias >of 123456[23][0-9] >Each user also has his number added to his permanent contacts to enable (on the cheap) a "call by PSTN if not online" poliy. > >The aim obviously being to have a 1-1 mapping between URI and allocated telephone number (we are still in the proof-of-concept phase and will move to DNS and ENUM based architecture at a later stage). > >Scenario 1: OK > PSTN user Up calls 12345621 - which is mapped to harry(a)dai-labor.de. > If harry(a)dai-labor.de is registered, his SIP UA rings and the call is established. > >Scenario 2: problem > harry(a)dai-labor.de wants to use his UA to place a call through the Softswitch. > The Softswitch "authenticates" (if you can call this authentication ;-( by looking at the > Contact header and comparing it to its database of numbers assigned to provisioned SIP Servers. > I therefore need to be able to specify a rewrite of the Contact header to > replace harry@<Contact IP:port> with 12345621@<Contact IP:port> > when the callee is of the form <number>@<whatever> > >I am aware that this would be strictly speaking not proxy but rather B2BUA behaviour, but would still be >interested to know whether anyone has a solution to this problem or whether we need to hack one ourselves. > >Many thanks in advance, > > Harry > >Dr. Harry Behrens >Projektleitung BIB3R >DAI Labor - Technische Universität Berlin >Sekretariat GOR 1-1, Franklinstrasse 28/29, 10587 Berlin > >Fon: +49 30 314 23383 >Fax: +49 30 314 21799 > >Email: harry.behrens(a)dai-labor.de > >http://www.dai-labor.de > > > >_______________________________________________ >Serusers mailing list >serusers(a)lists.iptel.org >http://lists.iptel.org/mailman/listinfo/serusers -- Jiri Kuthan http://iptel.org/~jiri/

Hallo, laut Beschreibung von http://iptel.org/ser/doc/modules/txt/vm.txt muss Mann viele Parameters einstellen. Aber das Beispiel von http://www.iptel.org/ser/doc/prerelease/x1294.html ist anders.

[Serusers] append_rpid_hf() and search()
by Alexander Mayrhofer 28 Oct '03

28 Oct '03

Hi, i'm adding remote party id information to certain SIP messages (to those destined to the PSTN gateway). After doing that, i try to search() the "Remote-Party-ID" header field for a specific string, and it seems to me that search() only works on the initial (received) SIP message rather than on the "current" modified message. Is that assumption correct? (i hope it's not :) If yes, is there another way to search SER's rpid information for a specific string? config snippet: if (!is_rpid_user_e164()) { append_rpid_hf(); xlog("L_INFO", "rpid added"); if (search("Remote-Party-ID:.*@1005")) { xlog("L_INFO", "rpid search succeeded"); }; ... thanx axelm

Hello List, Can anyone recommend some SIP Instant Messaging UA (linux and windows) that follows the specification word by word? I tried MSN Messenger 4.6 and 5 - both appears to have some problems (version 5 tries to send a MESSAGE with the INVITE method and gets back a BYE in response!!!!!!!!!!!!!). Thanks in advance, Dhiraj Bhuyan Security Research Engineer BT Exact Tel: +44 1473 643932 Mob: +44 7962 012145 Email: dhiraj.2.bhuyan(a)bt.com
