Thanks Victor - unfortunately Cirpack does not support North American networks.

[Serusers] Trying to use a remote mysql....
by Roger Lewau 09 Aug '06

09 Aug '06

I have been running SER quite successfully for a long time now. So tonight I dared to replicate the database to a remote server and changed the ser.cfg as follows. This is the two lines I changed in my ser.cfg filen #fifo_db_url="mysql://ser:heslo@localhost/ser" fifo_db_url="mysql://ser:heslo@192.168.12.140/ser" #modparam("auth_db|permissions|uri_db|usrloc|acc", "db_url", "mysql://ser:heslo@localhost/ser") modparam("auth_db|permissions|uri_db|usrloc|acc", "db_url", "mysql://ser:heslo@192.168.121.140/ser") Also updated serctl as follows: SQL_HOST=192.168.121.140 I then Stopped Ser, MySQL and restarted SER. It takes a long time then I get these line in the error log.. and ser fails to start. Aug 9 22:36:08 ns2 ser[43517]: new_connection(): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) Aug 9 22:36:08 ns2 ser[43517]: db_init(): Could not create a connection Aug 9 22:36:08 ns2 ser[43517]: ERROR: group_db_ver: unable to open database connection Aug 9 22:36:08 ns2 ser[43517]: group:mod_init(): Error while querying table version Aug 9 22:36:08 ns2 ser[43517]: init_mod(): Error while initializing module group Then I start the old local mySQL server again and restart ser and it springs to life. Why is that? I am not pointing to the local mysql server anymore... Have I missed something in the configuration? Even more strange, it seems that all authentication and accounting gets queried in the new server as I see can see the data in the new server alse sees the client connection from SER. Any one who can help with an explanation on this behaviour? Kind regards Roger

[Users] I can`t add new client by using openserctl add. Please help...
by Ferianto siregar 09 Aug '06

09 Aug '06

Dear all, Now, I try to test my openser configuration by using xlite. I tried to call from client to test the openser configuration that I have built working sucessfully. So, I must create a new user by using "openserctl add" command. But when i tried to do that, I got an error message. The error message said that " no rows effected". I think that this message said that I can not add a new user. For example: #openserctl add aldi aldi aldi(a)pcr.ac.id What can i do for solve this problem? I do hope anybody can give me a sugesstion.Please help me...Please Note: I use mysql for the database, and it can work goodly. ( I can show all the table that there is in openser database) Thanks with cheers, Ferianto --------------------------------- Do you Yahoo!? Next-gen email? Have it all with the all-new Yahoo!

[Serusers] Call limiting ?
by Alexandre Snarskii 09 Aug '06

09 Aug '06

Hi! As far as I know, SER does not have functionality of limiting number of calls on per-user basis. It was discussed years ago, and the reason for that was "We don't have ability to know is call still alive" (http://lists.iptel.org/pipermail/serusers/2004-November/013035.html) But, in April 2005, RFC 4028 (Session Timers in SIP) appeared, and it (at least theoretically) can be utilised to achieve knowlege of active dialogs, and, as result - on number of active calls. And this RFC looks like supported on Cisco gateways: U X.X.X.X:59104 -> X.X.X.X:5060 INVITE sip:aaaaaaa@X.X.X.X:5060 SIP/2.0. Supported: 100rel,timer,replaces. ^^^^^ Min-SE: 1800. ^^^^^^^^^^^^^^ User-Agent: Cisco-SIPGateway/IOS-12.x. Question: is this RFC/functionality planned to be supported in SER ? If not - are there any good intro on "How to write SER module by yourself" ? :)

[Serusers] SS7 Signaling & Gateways
by Max Clark 09 Aug '06

09 Aug '06

Hi all, I am looking for a _resonable_ cost SS7 solution to bundle with a TDM <-> SIP media gateway. I know the Cisco 5350 supports SS7 when bundled with an external solution - is there anything reasonably priced that will give me SS7 capability? Thanks in advance, Max -- Max Clark http://www.clarksys.com

[Serusers] presence_b2b UA
by Curt Moore 09 Aug '06

09 Aug '06

Hello all. I have been experimenting with the ser-0.10.99-xxx branch(es) and have a question about the presence_b2b module. I realize that the module is not yet fully complete but according to the documentation, when finished, the module should be able to take an inbound SUBSCRIBE request and then create a new SUBSCRIBE request outbound to another SIP entity or multiple SIP entities, ie Asterisk servers, hence the back to back functionality. What is the status of this functionality? Is anyone currently working to complete this functionality? I would be interested in helping complete or sponsoring the completion of this functionality. My intent is to have a SER server act as the central watcher database server and have all SUBSCRIBE and NOTIFY requests channeled through this SER server. This SER server will then generate new SUBSCRIBE requests out to each server in a farm of Asterisk servers and the Asterisk servers will then send NOTIFIES back to the SER watcher server. The watcher server will then take care of sending the NOTIFY messages to the correct watcher(s), according to the data in its watcher database. Is anyone currently doing anything similar to this using a different method or is using the yet to be completed B2B UA the correct/only way to accomplish this? Thanks, -Curt

[Users] Serial forking and accounting
by Andreas Granig 09 Aug '06

09 Aug '06

Hi, In a scenario A -> OpenSER -> B with the request being INVITE, B sends back 404 to OpenSER (the flag "db_missed_flag" of the acc module is set). OpenSER forks serially and sends another request to C, which is answered with 200. Now I get two acc records, the 404 from B because of the missed-flag and the 200 from C. Now is there a way to selectively suppress the acc record for the 404 in the failure route? Concretely I'd like to decide in the failure route whether that transaction is being accounted. Thanks, Andy

[Serusers] Gizmo Project API
by Voipers Portugal 09 Aug '06

09 Aug '06

Hi, Does anyone here used Gizmo Project API to build a softphone that can be used with other SIP servers like SER? My idea was to develop something like their softphone (Gizmo) but make it work with my own VoIP network. Any suggestions? Jose Simoes
