Several sources have told me that, once a call has been established, SER does not stay in the message path between the caller and callee. However, after examining some packet traces in Ethereal, I'm a little confused. I have the following setup: Caller -> SER -> Asterisk -> VoIP Provider -> Callee When I start tcpdump on Asterisk and place a call to the PSTN, the only devices that Asterisk is sending data to and receiving data from are SER and the VoIP provider. Doesn't this mean that SER does in fact stay in the SIP message path for the duration of a call?

[Users] Performance troubleshooting

by Dimo

Hi, I am having performance issues with openser running on Fedora. Here is the scenario: I have a openser which is sending calls to two asterisks, doing radius accounting and local syslog accounting, the database for user location is a local MySQL and the asterisks are load-balanced through dispatcher. i have modules: loadmodule "/usr/local/lib/openser/modules/mysql.so" loadmodule "/usr/local/lib/openser/modules/sl.so" loadmodule "/usr/local/lib/openser/modules/tm.so" loadmodule "/usr/local/lib/openser/modules/rr.so" loadmodule "/usr/local/lib/openser/modules/maxfwd.so" loadmodule "/usr/local/lib/openser/modules/usrloc.so" loadmodule "/usr/local/lib/openser/modules/registrar.so" loadmodule "/usr/local/lib/openser/modules/nathelper.so" loadmodule "/usr/local/lib/openser/modules/textops.so" loadmodule "/usr/local/lib/openser/modules/xlog.so" loadmodule "/usr/local/lib/openser/modules/avpops.so" loadmodule "/usr/local/lib/openser/modules/avp_radius.so" loadmodule "/usr/local/lib/openser/modules/acc.so" loadmodule "/usr/local/lib/openser/modules/options.so" loadmodule "/usr/local/lib/openser/modules/uri_db.so" loadmodule "/usr/local/lib/openser/modules/auth.so" loadmodule "/usr/local/lib/openser/modules/auth_db.so" loadmodule "/usr/local/lib/openser/modules/auth_radius.so" loadmodule "/usr/local/lib/openser/modules/dispatcher.so" Now the problem is that if i use sipp to send INVITE with 10-20 call attempts per seccond at one time ser just timeouts without answering for 1-2 seconds and sipp has to retransmit the packets. The timeout which sipp waits is 500ms so it should be enough. I have something like on 500 call attempts i get 700 retransmits. I will start stripping the config to troubleshoot but i was wondering if you can give me some idea what the problem might be or some good advice on troubleshooting, where should i look, and if you have any bes practices to recommend. BR, Dimitar

Re: [Serusers] RTP Proxy and SIP Proxy

by Andrey Kouprianov

Hi! This is just my own opinion. See inline > Hi, > > I World like to use SER with a point-to-multipoint sip softphone > application > That figures you need a conferencing capability. > This are my questions: > > 1- Is SER capable of handle that kind of signalling flow? SER has little to do with it. All depends on how the clients will generate their INVITEs, which SER will handle appropriately. > > 2- Is the RTP proxy able to fork RTP to more than one destination? > RTPproxy (as well as mediaproxy) is not a conferencing server but merely a node that helps NATed clients talk to each other, i.e. RTPproxy is a relay node. That's all. If you are looking for a conferencing software for audio, I would recommend using Asterisk. As for vdo and other multimedia, I have a little idea because, myself, Im struggling to find it. > > Thanks. Regards, Andrey.
