[Serusers] Re: SQL Accounting - Problems
by Darren Nay 15 Jan '04

15 Jan '04

Regarding the message below that I posted earlier today. I have some additional info.. I have tested this same accounting config on version 8.12 stable release of SER and it works fine. Is there bug in the SQL "acc" module for 8.12 CVS head? Thanks! Darren Nay ----- Original Message ----- From: Darren Nay To: serusers(a)lists.iptel.org Sent: Monday, December 29, 2003 11:51 AM Subject: SQL Accounting - Problems Hey All, I am trying to get SQL accounting to work within SER, but I am having a problem. The data is not being saved into the database. I've got the SER configured to use accounting. I've compiled the "acc" module with SQL support, and I believe that everything should be working.. However, I am getting the following errors in debug mode.. stateless - initializing 0(5814) Warning: uac does not spread accross the whole hash table Maxfwd module- initializing acc - initializing 0(5814) mod_init(): Database connection opened successfuly textops - initializing 0(5814) auth_db:mod_init(): Database connection opened successfuly 0(0) INFO: udp_init: SO_RCVBUF is initially 8192 0(0) INFO: udp_init: SO_RCVBUF is finally 262144 2(5816) INFO: fifo process starting: 5816 2(5816) SER: open_uac_fifo: fifo server up at /tmp/ser_fifo... 2(5816) WARNING: no fifo_db_url given - fifo DB commands disabled!

Also, my userloc registrations are being saved to the database in the "locations" table, and so I know that there isn't a problem with my mysql.so module. The database connectivity seems to be fine. I have attached me ser.cfg as well. If anyone knows why I am getting these errors, and why my accounting isn't being saved to the "acc" table in the database then I would very much appreciate the help! Thanks!

[Serusers] RE: S-CSCF IMS

Hello, For now I'm just interested in the S-CSCF because I want to make a lab implementation of the IMS so I only need the functions of the Home Network. P-CSCF is only need for roaming UE and I-CSCF can be optional. Why you you say that the extentions to SER will not be small? Have you already tried? Regards, João -----Original Message----- From: Kevin Chu [mailto:kevin.chu@viditec.com] Sent: segunda-feira, 12 de Janeiro de 2004 17:03 To: Joao Sampaio Cc: SER Users Subject: RE: S-CSCF IMS 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?

Hi, I need to upgrade the NAThelper module from 0.8.11 to 0.8.12 in order to have some of the lastest features and commands built in. But when I trying to do the rpm upgrade, i have error on failed dependecies on the "ser-mysql < 0.8.12 conflict with ser-0.8.12. Please advice is there anyway that I can be able to do the upgrade for the Nathelper only or is there anyway to bypass the mysql module. I am using Linux 9.0. Pease advice. best regards, shirley toh

[Serusers] "Out of Memory" errors
by Darren Nay 15 Jan '04

15 Jan '04

Hey All, Since we have ramped up usage from about 2 SIP phones to 30 SIP phones on our SER boxes to start some testing we are now getting a LOT of "Out of memory" errors in the syslog. We were originally running on a Sun Ultra60 with Solaris 9 but changed to an Intel box running Redhat 9 since we thought that there might be some memory leaks on Solaris. Unfortunately the problem exists regardless of the OS. When we start SER, it usually works fine for about 5 mins and then it starts giving the errors. We have plenty of memory on both servers that we have tested this on. Over a gig on each. Also, when I run top to check system resources it tells me that there is still over 800 meg of physical memory and over a gig of swap free even while SER is spitting out these errors. The errors that we are seeing the logs are as follows: Jan 14 13:32:45 jupiter /usr/sbin/ser[27179]: ERROR: build_req_buf_from_sip_req: out of memory Jan 14 13:32:45 jupiter /usr/sbin/ser[27179]: ERROR: print_uac_request: no pkg_mem Jan 14 13:32:45 jupiter /usr/sbin/ser[27179]: ERROR: t_forward_nonack: failure to add branches We get these over and over again in the syslog. Anyone know the reason that we are getting these errors? Is this a bug with SER? or misconfiguration somehow on our part? If so, how do we fix it? I have included our ser.cfg file as an attachment to this email, and I have also included debug output from SER as a seperate attachment. Any help would be very much appreciated! Thanks, Darren Nay - dnay(a)libertyisp.com

[Serusers] Failover Forwarding

14 Jan '04

I have a SER proxy setup and would like to forward all calls to a gateway. If that gateway is down i would like to forward the calls to a different gateway. Is this possible. I have tried. the following, if (method=="INVITE") { t_on_failure("1"); } t_relay_to_udp("MainGateway.com","5050"); . . . failure_route[1] { t_relay_to_udp("BackupGateway.com", "5060"); } but when the main gateway goes down the calls never get to the backup gateway and i get the following in /var/adm/messages Jan 14 15:40:55 sun /usr/local/sbin/ser[26727]: [ID 680273 daemon.error] ERROR: t_forward_nonack: no branched for fwding Jan 14 15:40:55 sun /usr/local/sbin/ser[26727]: [ID 204228 daemon.error] ERROR: failure_route: t_relay_to failed Jan 14 15:40:55 sun /usr/local/sbin/ser[26727]: [ID 749208 daemon.error] ERROR: on_negative_reply: Error in do_action i understand that this code would work if i were to create a different branch to send to a different address of the user, but i dont want to do that i want to try to reach the same user via a different gateway.
