[Serusers] How Many Nines?
by Jeremy A 20 Apr '08

20 Apr '08

Hello, I'm looking at a project which requires a higher than normal reliability for a SIP server. The project involves risk-of-life communications. The volume of traffic is quite low. I have been using SER in embedded applications for some time now without problems but I am now looking at a larger scale project. Assuming I can provide hardware server(s) with suitable characteristics, then : - How reliable is SER? - In each version? - In each module? Are there any well established high availability configurations for SER? Are there any risk-of-life deployments I can reference? We may well use SEMS for part of the project so the same questions apply. I'm not expecting 100% reliability, just a system that matches or exceeds present high reliability PABX deployments. If you are of the honest opinion that SER is not good enough, what SIP server products should I be looking at? Or is SIP not suitable full stop? Thanks in advance Jeremy

[OpenSER-Users] Error when using avp_db_load: "avpops:dbrow2avp: wrong field types in dbrow"
by Noel R. Morais 19 Apr '08

19 Apr '08

Hi all, I'm trying to load some attributes from DB to an avp and check if the value is greater than 0 (zero). I'm trying to limit the max sessions per user@domain. But when I execute "avp_db_load(..)" I get the error: "avpops:dbrow2avp: wrong field types in dbrow". I'm using unixodbc with oracle as DBRMs. The table DDL is: UUID(VARCHAR2), USERNAME(VARCHAR2), DOMAIN(VARCHAR2), ATTRIBUTE(VARCHAR2), VALUE(VARCHAR2), TYPE(NUMBER) Follow bellow the source: if (method == "REGISTER") { if ( avp_db_load("$fu","$avp(s:maxsessions)/avp_user_attributes") && avp_check("$avp(s:maxsessions)", "gt/0/g") ) { save("location") ; return; } else { sl_send_reply("503", "Service Unavailable"); return; } } I've checked the AVP source and the field types seems to be ok. I don't what to do. Thanks in advance, Noel ps: Sorry about the poor English

[OpenSER-Users] Radius with additional parameters
by Alex Massover 19 Apr '08

19 Apr '08

Hello! I see how I can receive additional parameters from Radius server via AVPs. But I wonder if it's possible to send additional parameters (headers) to Radius server in requests? For example I want to pass to Radius server P-Asserted header, in case that I need validate it? -- Best Regards, Alex Massover VoIP Development Manager Jajah Inc.

[OpenSER-Users] mi_datagram module bind failure
by Sigrid Thijs 18 Apr '08

18 Apr '08

Hi, we're setting up OpenSER 1.3.0 on a FreeBSD system, with the mi_datagram module configured, and when we start up openser, we get the following error: /usr/local/sbin/openser[3139]: NOTICE presence:child_init: init_child [1] pid [3139] /usr/local/sbin/openser[3138]: ERROR:mi_datagram:mi_init_datagram_server: bind: Invalid argument /usr/local/sbin/openser[3142]: NOTICE presence:child_init: init_child [4] pid [3142] /usr/local/sbin/openser[3138]: CRITICAL:mi_datagram:pre_datagram_process: function mi_init_datagram_server returned with error!!! /usr/local/sbin/openser[3138]: ERROR:core:start_module_procs: pre-fork function failed for process "MI Datagram" in module mi_datagram In the openser configuration: modparam ("mi_datagram", "socket_name", "udp:[ip.add.ress.here]:5068") We checked that the port is not in use. Note that this is working fine when running the same openser version on a linux based system. We are also not having this issue when we specify a UNIX socket. Do you have any idea what could be wrong? kind regards, Sigrid

[OpenSER-Users] Openser xmpp module configuration problem
by Gaoqiang Qian 18 Apr '08

18 Apr '08

Hi, I have now running a openser server 1.1.0 notls and have installed another openser 1.3.1 with xmpp module configured as the server-mode. Could you tell me how could I change my main sip server(openser 1.1.0 notls) configuation to configure it send sip message to the xmpp gw. Or is there anyway that I could just have one openser server(1.2.x above) along with xmpp module installed. And have it configured as SIP server + XMPP server + SIP-to-XMPP gateway? Could you show me some configuration example to achieve this if possible? Thanks in advance.

[OpenSER-Users] PUA/PUA_MI: More than one Publish sent
by Schumann Sebastian 17 Apr '08

17 Apr '08

Dear all I am using OpenSER 1.3.1 branch release R3936. I face some bad behaviour using pua and pua_mi modules. I publish presence states via the management interface. Sometimes, it happens that multiple PUBLISH message are sent by one request. Unfortunately, there is no "system" or oder when this occurs. It just happens after some publications. In case of an expiration (Expires=0, E-Tag .) it is not that bad, I receive the log message: ERROR:presence:update_presentity: No E_Tag match. In case of publication (Expires=-1, E-Tag .) it is very bad: After publication, he receives also two similar messages, and threats both PUBLISH messages as two different ones. Thus, creates two different presentity entries with different E-Tags. If the state is expired now via MI (Expires: -1, E-Tag .) only one of the E-Tags is removed. The second stays in the presentity table and the user still appears online. Any ideas what can be the reason and how to solve it? Best regards Sebastian

Could you help me doing the troubleshooting of this ? What else should I verify ? Regards, Pascal

There are parameters that should point to the same DB as both openser and openserctl should operate on the same DB.
