[Serusers] RE: S-CSCF IMS
by Kevin Chu 12 Jan '04

12 Jan '04

Hello, As my understanding, I don't think it is possible to configure SER to work as a S-CSCF without any modification. On the other hand, I don't think the modification or extension will be small for SER working as a S-CSCF in IMS. I am just curious, but why you are interesting about using SER as S-CSCF only? How about the others, like P-CSCF and I-CSCF?

Thank you for your answers. I have read the manuals from iptel.org, but I can't find there all the answers. In 'SER HowTo' Manual, it's written to run ser_mysql.sh in order to create ser database. And then, you should be able to see ser tables and ther users 'ser' and 'serro' doing mysql> select * from user; mysql> show tables; Well, my problem is that I can see subscriber table, and add users with serctl command, but I can't see 'ser' and 'serro' users and I don't know whether this could be the problem. I try to connect my SER whit a SIP client, and always obtain this message: Status:478 Unresolveable destination (478/TM) Any idea? In other hand, I have installed serweb in order to manage SER. But I have a few options. I can log and see the users from subscriber table, and see several statistics, but anything more. Is this usual? Do I have to install another modules to manage users? Again, thank you very much for your time, and excuse me if I ask a lot of questions, but I'm newbie around SIP.

[Serusers] serctl problem
by Jan Janak 12 Jan '04

12 Jan '04

Hello, We found out yesterday that there is a problem in serctl. If you try to add an alias using serctl utility, it expires immedialy. serctl creates expires value that is too big and variable that contains the expires value overflows. The problem was fixed yesterday in both, stable and unstable, CVS branches. To fix the problem, you can either edit serctl script and change the line FOREVER_REL=1073741823 to FOREVER_REL=1003741823 or update the script from the stable CVS branch: cd sip_router cd scripts cvs update sc and then reinstall the script (either using make install or by hand -- cp sc /usr/local/sbin/serctl) We apologize for the inconvenience. Jan.

[Serusers] Configuring SER
by CURRO_DOMINGUEZ 12 Jan '04

12 Jan '04

Hello, I'm trying to install SER to do some test on my LAN. We only have SER and a client. But installing SER has became a difficult task. I have run ser_mysql.sh to create de Ser tables. I can see the tables, but I can't see anything when I write: mysql> select * from user; Error 1046:No database selected; However, I can connect to ser database and show all the tables. Do you have any idea? I have a second question. Which .cfg should I use to configure SER? Default, User Agent or another one? I just want to create a domain with a server and a client on the same LAN for test purposes. Thank you very much for your time. Curro

[Serusers] Cant get Accounting working at all
by Arnd Vehling 12 Jan '04

12 Jan '04

Hello, after implementing very basic pstn-routing ive tried to get accounting to a mysql database working. Unluckily with no success yet. Ive read the acc/README, several example configs and all i could find on the mailing list archive but i still cant get it to work. According to the docs i configure the acc module after loading like this: --- # # Accounting Setup # modparam("acc", "db_url", "mysql://yyy:yyyy@localhost:3306/ser") modparam("acc", "log_level", 1) modparam("acc", "log_flag", 1) modparam("acc", "failed_transactions", 1) modparam("acc", "log_fmt", "miocfst") --- Then i added "setflag(1);" at various location within my simple ser-script. First i added it just b4 the "t_relay()" then i tried various other locations until i finaly added: --- setflag(1); setflag(2); --- at the very start of the script. All which happens is that the ser-router writes some errors into the syslog: --- Jan 10 12:56:18 gk /usr/local/sbin/ser[13285]: BUG:tm:register_tmcb: no transact ion found Jan 10 12:56:18 gk /usr/local/sbin/ser[13285]: ERROR:acc:acc_onreq: cannot regis ter additional callbacks --- and --- Jan 10 11:51:12 gk /usr/local/sbin/ser[12694]: ERROR:acc:acc_onreq: cannot regis ter additional callbacks Jan 10 11:51:12 gk /usr/local/sbin/ser[12693]: ERROR: extract_body: message body has lenght zero Jan 10 11:51:12 gk /usr/local/sbin/ser[12693]: ERROR: force_rtp_proxy: can't ext ract body from the message Jan 10 11:51:12 gk /usr/local/sbin/ser[12693]: ERROR: on_reply processing failed --- I am using version: --- version: ser 0.8.13-dev-23-merged (i386/linux) flags: STATS:Off, USE_IPV6, USE_TCP, DISABLE_NAGLE, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, FAST_LOCK-ADAPTIVE_WAIT ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535 @(#) $Id: main.c,v 1.174 2003/11/26 23:43:59 andrei Exp $ main.c compiled on 21:37:37 Dec 27 2003 with gcc 2.95 --- Below you find the complete ser.cfg.
