The level of granularity of load balancing is on a per-IP basis, not per-transaction (LVS only does L3 load-balancing, not L4-7). But assuming a reasonable value for the persistence timeout, there should be no problems with SIP transactions (and I haven't experienced anything problematic). Ldirectord also supports SIP health checks (they're pretty basic OPTIONS requests, but it's something), and will fail over to working SIP proxies. Of course, in-progress transactions will fail as the OpenSER process on one box doesn't have the stateful knowledge of the other.

[Users] forwarding requests...
by Frogger 06 Dec '06

06 Dec '06

I am trying to forward requests so that the request is completely gone and the UA is forwarded to the final destination with no signaling from the forwarding system. For example: "5551212@" would be forwarded to 1.1.1.2 but 1.1.1.2 would not get a redirect request from 1.1.1.1 rather, directly from the UA. Any thoughts? Thanks!

[Users] Jabber (Authentication to the Jabber server failed)

Hi all, I'm trying to configure jabber module in OpenSER and this is what I get when sending a message from Ekiga to a Jabber user: "0(26030) XJAB:xj_jcon_connect: socket [7] 0(26030) XJAB:xj_worker: auth to jabber as: [teste2] / [xxx] 0(26030) XJAB:xj_worker:26154: Authentication to the Jabber server failed ... 0(26030) XJAB:xj_jcon_disconnect: -----START----- 0(26030) XJAB:xj_jcon_disconnect: socket [7] 0(26030) XJAB:xj_jcon_send_presence: -----START----- 0(26030) INFO: signal 13 received 0(26030) XJAB:xj_jcon_send_presence: Error - presence not sent 0(26030) INFO: signal 13 received 0(26030) XJAB:xj_jcon_disconnect: error closing stream 0(26030) XJAB:xj_jcon_disconnect: -----END----- " "jusers" table has only one entry: juid => 1 jab_id => teste2 jab_passwd => teste2 sip_id => sip:teste2@voip.mydomain ( This is the Ekiga user) type => 0 "openser.cfg" modparam("jabber", "db_url","postgres://openseruser:mypass@192.168.95.78/sip_jab") modparam("jabber", "jaddress", "192.168.95.135") modparam("jabber", "jport", 5222) modparam("jabber", "jdomain", "xmpp.mydomain=*") modparam("jabber", "registrar", "jabber_gateway(a)127.0.0.1") modparam("jabber", "workers", 2) modparam("jabber", "max_jobs", 10) modparam("jabber", "cache_time", 600) modparam("jabber", "delay_time", 90) modparam("jabber", "sleep_time", 20) modparam("jabber", "check_time", 20) Any sugestion?

[Users] SER/OpenSER + Asterisk + Queue
by lists＠infoway.net 05 Dec '06

05 Dec '06

We are in the process of redesigning our single Asterisk server that handles several queues for our clients. We offer our clients hosted queueing/call center basic services. All the agents are in remote locations behind NATs using either softphones or PAP2-like devices. What we would like to accomplish is setup a SER or OpenSER ("SER") server(s) in front of our Asterisk box such that all incoming and outgoing calls are handled by SER. The basic idea is to get set up for scaleability and redundancy. The goal is to be able to add additional Asterisk servers to spread our queue loads. Nothing fancy, maybe just separate clients on different boxes (not load balancing queues across multiple Asterisk boxes since that a totally different scope of project). We could then add additional SER boxes to protect our inbound and outbound SIP gateways to our SIP providers (all our calls are SIP-based - e.g. no TDM circuits). Lastly, all our agents would register against the SER server(s) instead of directly to the Asterisk boxes. Has anyone done this? Can anyone point me to some tips/documentation? Does anyone care to comment? If agents login using AgentCallBackLogin, will Asterisk know where the agents are and send the calls to them via SER? Thank you so much in advanced. - Daniel

RE: [Users] Using Openser's CPL module...
by Marvin Ottley 05 Dec '06

Good day Bogdan and Nicolas, Thanks for your prompt response. I tried the recommended command: "openserctl fifo LOAD_CPL sip:user@domain /path/his_cpl_file.xml" And the response I received was: "500 command 'LOAD_CPL' not available." I'm using the release version of openser 1.1. Marvin -----Original Message----- From: users-bounces(a)openser.org [mailto:users-bounces@openser.org] On Behalf Of Bogdan-Andrei Iancu Sent: Tuesday, December 05, 2006 5:43 AM To: Nicolas Palix Cc: users(a)openser.org Subject: Re: [Users] Using Openser's CPL module... Hi Nicolas, the DB upload must be done via the proxy because the DB contains not only the CPL script in XML format, but also in a pre-compiled format of it in binary format. This pre-compiling is done at upload time. You can take it as limitation, but you also have full liberty to implement any transport mechanism for the CPL scripts (from user to server) (like CGI and HTTP) - but on server side, the DB storage must be done via openser. regarding the docs - you are right, it is a bug there - the module requires a DB module (that's why db_url is mandatory), but this is not properly documented. I will take care of it. thanks and regards, bogdan Nicolas Palix wrote: >Hi all, > >Is there some limitations ? >What about email tag ? >The documentation does mention anything. > >Futhermore, "db_url" is mandatory but DB module are not mentioned as mandatory >in the "Dependencies" section. > >Regards, > >Le mardi 05 décembre 2006 09:14, Bogdan-Andrei Iancu a écrit : > > >>Hi Marvin, >> >>you have two options to upload a CPL script into DB (both require your >>server up and running) >> >>1) use FIFO/MI command "LOAD_CPL" : >>:LOAD_CPL: >> >>username >>cpl_filename >>( openserctl fifo LOAD_CPL sip:user@domain /path/his_cpl_file.xml ) >> >>2) use the REGISTER request >>http://www.openser.org/docs/modules/1.2.x/cpl-c.html#AEN272 >> >>regards, >>bogdan >> >>Marvin Ottley wrote: >> >> >>>Good day all, >>> >>>I'm trying to use the CPL module and I'm having trouble figuring out >>>how to load the cpl xml script into the cpl database. >>> >>>Thanks for your pointers >>> >>>Marvin >>> >>>------------------------------------------------------------------------ >>> >>>_______________________________________________ >>>Users mailing list >>>Users(a)openser.org >>>http://openser.org/cgi-bin/mailman/listinfo/users >>> >>> >>_______________________________________________ >>Users mailing list >>Users(a)openser.org >>http://openser.org/cgi-bin/mailman/listinfo/users >> >> > > > _______________________________________________ Users mailing list Users(a)openser.org http://openser.org/cgi-bin/mailman/listinfo/users

[Users] Couple of usagequestions (trunking/alias, )
by Andreas Sikkema 05 Dec '06

05 Dec '06

Hi, I'm running an OpenSER server and I've got a couple of usage questions I'd like some pointers on how I can implement them. - I want to link multiple incoming telephone numbers to one single account so 123456 and 45678 and 999933 can all point to the account customer1 Basically I want to do SIP trunking, but with requiring the CPE to authenticate itself. How do I do this? - I'm now using an Asterisk server to do some incoming call routing (mainly some call forwarding scenarios) and I'd like to remove the Asterisk dependency. How do I retrieve values based on the called destination from a database? I've tried looking at AVPops, but haven't yet found any clear documentation on how to use it. Thanks! -- Andreas Sikkema

[Users] Load Balancing
by Thomas Deillon 05 Dec '06

05 Dec '06

Hi all, I try to use SER as a load balancer with the dispatcher module. All SIP/RTP request are load balanced and, in a LAN, it's working. With phone with a public address ip, it's work too. But my problem it's with NATed phones... The ser change the source ip address and so, the nat=yes option in asterisk cannot work!! (I make registration on ser servers) I wanted to change the "from header field" in the ser and put the IP source, but it seams impossible. Do you have an idea for my problem? Thanks a lot, Thomas Deillon

[Users] qop authentication support
by Klaus Darilion 05 Dec '06

05 Dec '06

Hi! Reading openser's docs about qop, it looks like openser supports qop. turning qop on with www_challenge("", "1") activates the qop parameter: WWW-Authenticate: Digest realm="foo.bar", nonce="457553154ed7b9d93effa4118b4fe21f11b7f887", qop="auth". Openser advertises only qop=auth. Looking at the source code I get the impression that auth-int is supported too. How can this be activated? regards klaus -- Klaus Darilion nic.at
