Hi, I have some experience with Asterisk PBX and I read ser is more powerful. I have Polycom IP 600 phones and I will like to know if someone try to use the "sharing" line signaling with ser. I install ser and I register my phone. Can someone help me please to forward the calls thru my * PBX? Any suggestion is more than welcome. Best regards, Chris HARIGA

[Serusers] Authentication failure (was:problem running ser in the foreground)

by daryl

thank you girish and mirian for your replies. indeed i now have ser running in the foreground. i am however having difficulties with authentication and registration. i am able to register via sipsak on the same machine running ser. i am also able to register using sipsak from my another (home) network (which is behind a nat'd firewall) if i use the -H option and explicitly set the hostname. however i am unable to register using iether kphone or sjphone. my ser.conf looks like this: loadmodule "/usr/local/lib/ser/modules/mysql.so" loadmodule "/usr/local/lib/ser/modules/sl.so" loadmodule "/usr/local/lib/ser/modules/tm.so" loadmodule "/usr/local/lib/ser/modules/rr.so" loadmodule "/usr/local/lib/ser/modules/maxfwd.so" loadmodule "/usr/local/lib/ser/modules/usrloc.so" loadmodule "/usr/local/lib/ser/modules/registrar.so" loadmodule "/usr/local/lib/ser/modules/auth.so" loadmodule "/usr/local/lib/ser/modules/auth_db.so" modparam("usrloc", "db_mode", 2) modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "password_column", "password") modparam("auth_db", "password_column_2", "ha1b") modparam("rr", "enable_full_lr", 1) any help, hints or rtfm's would be appreciated... thanks, daryl Girish wrote: > Hello, > > --- Marian Dumitru <marian.dumitru(a)voice-sistem.ro> wrote: > > > >> Note that the configuration values from SER config file have priority >> over the command line parameters.

Re: [Serusers] stateless/statefull processing and INVITE method retransmissions

by Michael Kaufmann

Hi again, I see that the registrar part of SER is using SL module. I am trying to build my own authentication - simply use the PRE_SCRIPT_CB callback (without using the configuration file) to send some of the data in SIP requests to my own server without reparsing the message. The problem occures when the user is not authorized - when the callback return value is 0 no answer is sent back to the client, and I would like to send him the not authorized reply. How can it be done if the only way to hook request answers is using TM? Another problem - I really didn't understand from the documentation if the authentication module is able to do what I described above (my server might be in another computer and has to be able to handle more than one SER - It might even exchange data with the SIP clients) Can someone give me an idea of how to implement the SER side module for such a server?

[Serusers] mysql module

by S Shah

I have a redhat linux server and I installed SER version 0.8.14. I'm unable to find the mysql script file to download for this version. For SER version 0.8.12 the file ser-mysql-0.8.12-0.i386.rpm is available. I tried running that package after I installed 0.8.14, but got a message saying that the version of SER was not compatible. How can I configure mysql for SER version 0.8.14? Thanks. Sher

[Serusers] Call Admission Control on SER

by verbalkint＠virgilio.it

Hi all, I have a very urgent question and I would know if anyone is dealing with CAC on SER....exist any methods/function in statefull proxy mode to count simultaneous calls coming from the same calling party number (from HF), feeded from one IP PBX (like Asterisk) with just one single digest account and one permitted uri, and in case setting two call thresholds (one for the allowed simoltaneous calls and one for the allowed call per second)? If yes, is it possible blacklisting/barring this user (in a cached table with function like file permission.deny) for some time/forever if the call counters exceed limit settled by above threshold? 10nx, Verbal
