Hi! I just found this parameter in sl and presence module, but the usage is not described well. What is it's purpose? I guess that the presence module exports the totag into this AVP and the sl module use this totag in its response. I think it is not a good idea to have it configureable in 2 modules. We had the same problem with the "use_domain" parameter in several modules which was fixed recently. Maybe this can be fixed the same way - having it configurable in sl module, and presence module look ups the value on loading (or generate a error if not defined). Further, the presence module's parameter documentation lack the default values. regards klaus

However ser is very good at doing message processing, forwarding and all sorts of "tricks" * RTP may be handled by three separate software components: rtpproxy, mediaproxy, and sems (mediaproxy is not an iptel.org project, the others are). SER modules (nathelper and mediaproxy) are used to communicate with these external components (locally or over udp) and for mangling the SDP payload * Your measurements will probably need to follow the media path of a normal session. If not, you will not be able to measure for example real latency on your ex. rtpproxy server(s). SEMS is a very good general-purpose media server, while rtpproxy/mediaproxy are more dedicated for proxying of rtp for NAT-purposes etc * Hence, you probably need to implement sdp loopback intp the rtp handling component. SEMS may be the easiest way due to its very modular and powerful plugin interface (it's also a B2BUA). However, as sems don't stay in the media path except in conferences etc, you don't really measure "real world..." * I suspect you can create a ser module (or extend nathelper) that implements the basic loopback stuff using rtpproxy without touching rtpproxy (too much) > As for development, ser has a very efficient core exposing a module > interfaces.

The basic concepts are still relevant. It has not been updated to cover to the attribute value pairs and the selects. We are currently focused on the user documentation for the next release, but we are debating what the next steps are. A how-to for module development is already on the list, possible with a retouch of the old developers guide. You can start out with one of the simpler modules (like textops or dispatcher) and modify to your needs.

[Serusers] Radius Accounting Help
by Arun Kumar 28 Dec '06

Hi, I've configured my radius + mysql and openser. Now openser is sending accounting packet to radius server and I'm able to see accounting packets coming to my radius server but the problem is : Its sending the Acct-Status-Type = Start Service-Type = Sip-Session Sip-Response-Code = 200 Sip-Method = Ack packet twice and then it shows rlm_radutmp: Login entry for NAS august port 5060 duplicate and then two stop packet: Acct-Status-Type = Stop Service-Type = Sip-Session Sip-Response-Code = 200 Sip-Method = Bye and then it shows rlm_sql (sql) in sql_accounting: stop packet with zero session length and after second stop packet it shows rlm_radutmp: Logout for NAS august port 5060, but no Login record please help. thanks arun

[Users] lock error with configuration mistake
by Jean-François SMIGIELSKI 28 Dec '06

28 Dec '06

I wrote this message a few days ago: http://openser.org/pipermail/devel/2006-December/005103.html I am sorry for the lack of informations I gave, I could investigate a little bit about it. Here is the full context: When an INVITE comes, I dispatch and t_relay it to a server. If the transaction makes an error, I wrote in the configuration to manage this whith a failure route. In this failure route, I dispatch and t_relay the transaction to a server for an other service. And then appears an strange error : * with an openser compiled with the default flags, the UDP that received the last UDP packet infinitely loops on the "sched_yield" function, in the "tsl" function in fastlock.h. * with an openser compiled with flags that make him use pthread for locking purposes, the UDP process hangs, while trying to get a mutex. It appears I forgot a call to append_branch in the failure route. Maybe the process tried to get the same lock twice. Is it known for OpenSER 1.1.0? If it is, is it corrected in later stable releases ? Thanks a lot for your answer!
