[OpenSER-Users] renaming of database modules
by Henning Westerholt 06 Feb '08

06 Feb '08

Hi all, the database modules and the supporting infrastrucure in the OpenSER core are heavily reworked in the trunk version at the moment. Common functionality that is present in all database modules were integrated in the core, new functionality have been added. Its planned to unify the overall behaviour and structure of all modules that are interfacing with databases, to make them more maintainable, more safe and also more bug-free. Important foundations for this changes have already been created. As part of this process the database modules names were changed. All these module names are now prefixed with 'db_'. The new names of the modules are now db_mysql, db_postgres, db_unixodbc, db_berkeley, db_text, db_flatstore. If you use one database module with the trunk version, you must change some parts of the configuration. Old module configuration: loadmodule "mysql.so" modparam("mysql", "ping_interval", 300) modparam("mysql", "auto_reconnect", 1) New module configuration: loadmodule "db_mysql.so" modparam("db_mysql", "ping_interval", 300) modparam("db_mysql", "auto_reconnect", 1) The database URLs for modules that connect to a database, e.g. usrloc don't need to be changed, if you use mysql, postgres, unixodbc or flatstore DBs. For the dbtext and db_berkeley modules the new database URLs are: modparam("usrloc", "db_url", "text://my-database-path")" modparam("usrloc", "db_url", "berkeley://my-database-path")" (you need to adapt the path to your setup, of course). If you encounter any bugs that were introduced during this change, please open a bug report on the tracker. Best regards, Henning

[Serusers] (SER + OpenXCAP) Presence Authorization problem
by Guhan P 06 Feb '08

06 Feb '08

Hi All, I am using SER 2.0 and OpenXCAP 0.9.7 and facing problem in implementing Presence Authorization using XCAP in my project. I have done the following:- User A (User_A.pcap(attachment)): 1.Registered with SER. 2.Published A's info into SER. 3.Subscribed for it's 'presence.watcher info' 4.Transferred presence_rules.xml(which contains rules to allow B to see his presence status) to OpenXcap. Following debugging messages were printed (while transferring presence_rules file ) in OpenXcap: ************************************** Feb 6 12:15:40 sips openxcap[2557]: [-] Starting factory <twisted.web.xmlrpc._QueryFactory instance at 0xb3cde68c> Feb 6 12:15:40 sips openxcap[2557]: [Uninitialized] error: Error while notifying OpenSER management interface for 'user' a@: Connection was refused by other side: 111: Connection refused.

[OpenSER-Users] Sending Text Response from Openser to client
by Ali Jawad 06 Feb '08

06 Feb '08

Dear All I would like to change the messages that are sent back from the openser server to the client is this possible using sl_send_reply for example ? I have tried sl_send_reply in the route[1] but it pops up a dialog box and it seems to break the calls. Can anyone tell me where to get more info about such a scenario. Or suggest any solutions ? Thanks

[OpenSER-Users] Store Encypted Pwds in MySQL DB
by Ali Jawad 06 Feb '08

06 Feb '08

Hi All I am migrating a couple of thousand users from an old sip server with mysql support to openser with mysql support, the thing is that in the old server the passwords were encrypted using 3DES and stored encypted in the MySQL db ...the old SIP server received the passwords using plaintext converted them to 3DES using perl script and the compared the result to the password stored in the MySQL DB. Any ideas about how to achieve something like this in OpenSER "? I.e. hash the passwords ? Or any other solution ? I have seen some hashed entries in the MySQL db could they be used for such purposes ? Thanks

Re: [OpenSER-Users] MSILO back notify not working
by Iñaki Baz Castillo 06 Feb '08

On Monday 04 February 2008 19:02:30 Dan-Cristian Bogos wrote: > Iñaki, > > this code should do the magic: > > if (!t_reply("202", "Accepted")) > { > sl_reply_error(); > }; I use exactly that code: t_newtran(); if (m_store("$ru")) { if (!t_reply("202", "Accepted")) sl_reply_error(); } But there is not a created MESSAGE by OpenSer to the sender. I've set "debug=4" and no errors appear, the message storage is done correctly and OpenSer doesn't try to send back a new MESSAGE as notification. I'd like to insist a bit in the fact that what I'm trying to get is receiving a **new** MESSAGE generated by OpenSer as notification to the sender, not just the "202, Accept" reply (that is a reply, not a MESSAGE). Please Dan, can you confirm that MSILO module should generate and send a new MESSAGE as notification to the sender, and not just a "202 Accepted" reply? Thanks a lot. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[OpenSER-Users] can't get openser to start
by Bill Brownrigg 06 Feb '08

06 Feb '08

My openser.cfg runs and the modules load but then I get this message: "ERROR: tcp_init: bind(7, 0x811d384, 16) on 127.0.0.1:5060 : Address already in use" Environment is Red Hat and OpenSER 1.1.0 We do not need TCP as we only use UDP. Is there a simple way to remove TCP from the OpenSER environment? If not, how do we figure out what is causing the conflict? The box used to run Asterisk but it was shut down. TIA, Bill

[OpenSER-Users] newbie questions
by Doug McLetchie 06 Feb '08

06 Feb '08

Hi all, I've been reading through the documentation online fore a few days, and I've read through a lot of the user & developer artchives. I'm trying to figure out if OperSER is the right proxy solution for the problem that I'm trying to solve. I was hoping that I could get a few pointes from some more experienced users. My first question is really simple... I must have the terminology wrong, otherwise I'm sure that I would have found the answer by now. I have a big expensive gateway, but it can't do a few things that I really want to do. I'm hoping to augment my big expensive gateway with OpenSER, so that I can do some specific routing. I want my network to look something like this: -------------- (Public IP network) (Private IP network) .----------. | carriers |-----. '----------' | .-----------. '----| Big | .-------. | Expensive |----| Proxy | .------. .----| Gateway | '-------' | PBXs |---------' '-----------' '------' ---------- my solution involves customer-premise based PBXs that my company makes in house. I want the gateway to act as a session border controller. It'll take care of forwarding me media, and it'll take care of protecting my proxy from the public internet. For inbound calls (calls coming from another carrier to my big expensive gateway & destined for a specific PBX), I'd like my gateway to send the call to the proxy, who will determine which PBX to send the call to, and then send the call to to correct PBX via the Gateway. I don't understand how to set up OpenSER to send the call via the Gateway. If I provision the static ip address of the PBX in the proxy, won't it try to send directly to that IP address instead of sending it to the Gateway? I think that the feature that I'm looking for is something like an outbound proxy, for the proxy. (does that make sense?) Sorry to write such a long e-mail to the mailing list! I wanted this to be descriptive enough that you all would know what I mean. THANKS! --Doug ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo! Mobile.
