[Serusers] ser-0.9.6: modules/postgres bugreport & patch

by Alexandre Snarskii

Hi! I'm running ser-0.9.6, on FreeBSD 6.1-stable, database backend is postgresql version 8.1.3. Today I got errors in logfiles, saying: messages.2.bz2:May 29 14:35:03 <XXX> /usr/local/sbin/ser[51448]: ERROR:avpops:dbrow2avp: dbrow contains NULL fields The similar problem reported in: http://lists.iptel.org/pipermail/serusers/2005-May/019681.html with much more detailed description of error, database contents and config samples. Patch is trivial, and looks more like a fix to copy'n'paste error: in mysql/val.c function str2val states: if (!_s) { memset(_v, 0, sizeof(db_val_t)); VAL_TYPE(_v) = _t; VAL_NULL(_v) = 1; return 0; } VAL_NULL(_v) = 0; and the last line mentions that 'well, that's value is not NULL'. In postgresql/db_val.c, line 182, function str2valp, the same statement is the: if (!_s) { DLOG("str2valp", "got a null value"); VAL_TYPE(_v) = _t; VAL_NULL(_v) = 1; return 0; } without explicit notification that this is not-NULL value. More than, nowhere else in this function VAL_NULL(_v) not set to 0. So, if a value _v.val contained anyting but 0 at the function start, resulting value will be threated as NULL despite the fact, that _s is NOT NULL. Patch is obvious, just add VAL_NULL(_v)=0; after cited block (line 188) and everyting will be ok. At least for me it's ok for some hours :)

[Serusers] SER Nokia CANCEL Problem

by Abdul Qadir

Hi , I tried to call from one nokia sip (E61 and other models )phone to another nokia sip phone. The call works fine. The problem comes only when I call from Phone A to Phone B and then immediately cancel the call(from Phone A). The Phone A will hangup the call as it sent CANCEL but the SER will ignore this CANCEL and still send INVITE to Phone B resulting in a ghost call situation. I tried to capture a log of message and found that Phone A "CANCEL" message is received on SER even before any provisional response from Phone B. Therefor SER doesnot relay this CANCEL request to Phone B. I even checked RFC which clearly says that UAC should not send CANCEL untill it receives any provisional response. I talked to Nokia expert and they said the 100 Trying message from your server is considered as provisional response, therefor behaviour of client is absolutely correct. Is there any way I can stop 100 Trying message and still run statefull SER, so that I can verify what nokia said. Any ideas suggestions are welcome. Thanking you all in advance.

[OpenSER-Users] [IMC module] What are imc tables for?

by Iñaki Baz Castillo

Hi, in order to use chat rooms I'd like to manage them just from a web interface that handles imc_rooms and imc_members table, but sincerely I don't know how to use them, I don't see doc about hot to use the tables. What I'd like is to have "fixed" chat rooms without the need of creating them with commands, but via web. Could anyone explain me how to use those tables? Please, explain me with this example: - I want a chat room for domain "domain1.org" and name "chat1". - I want three members for that room: - user1(a)domain1.org - user2(a)domain1.org - other_user(a)other_domain.org Could you fill the tables please? ** imc_rooms table ** name domain flag ** imc_members table ** username domain room flag What is flag for? I suppose it's for features as private/public tables and so. Maybe it's not possible to manage those tables and the only way is using chat commands? Thanks for any help and best regards. -- Iñaki Baz Castillo

[OpenSER-Users] [group module] Realtime in 're_grp' table?

by Iñaki Baz Castillo

Hi, I need the possibility of users in many groups. This is not allowed by "grp" table where username, domain and grp are UNIQUE key. So It could be valid for me using "re_grp" table and managing numeric groups. But "re_grp" table doesn't allow realtime (if I do a INSERT or UPDATE in the table I need to restat OpenSer). Is not possible to use "re_grp" table in realtime mode? Thanks. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[OpenSER-Users] Announcement: devel.openser.org available

by Henning Westerholt

Hello, i'm happy to announce that the 'devel.openser.org' server, sponsored from my company 1&1 Internet AG, is now available. This machine hosts services for developers, but some of them are probably also useful for users: 1. Daily creation of debian builds (etch i386 and amd64) of the trunk for easily testing. 2. A read only svn mirror of the complete repository for better subversion performance especially outside the USA. 3. The build and testing framework "buildbot" for continous monitoring of the status from trunk and branches. 4. Doxygen code documentation with graph generation for better understanding of the code and module dependencies. You'll find at http://devel.openser.org/ the indivdual addresses of the services. This page will probably be moved to www.openser.org after the migration of these server.

[OpenSER-Users] How to expose the expires value in REGISTER

by Robert Dyck

I am wondering how to expose and test the value of the expires parameter in a REGISTER request. I am experimenting with openser as the basis for a home phone network. I use multiple devices with the same user ID. They register locally ( with no reply ) and with an external service provider. The contacts are mangled to show the public address of openser. Multiple registrations result in a single AOR at the external registrar. Incoming calls from the outside are forked and ring the local phones. Local phones can also call each other without the hairpin problem associated with STUN enabled phones. The problem is that a softphone will deregister when it is closed or its profile changes. This would deregister the AOR at the external registrar. The remaining phones could not receive calls from the outside until they refreshed their registrations. I would like to prevent deregistration at the external registrar unless the phone that was deregistering was the only remaining one. The first step would be to identify REGISTER messages where the expires value is equal to zero. Any thoughts? Thanks Rob
