[Serusers] SER and rtpproxy stability
by Steven Wang 27 Nov '07

27 Nov '07

Hello We use SER and rtpproxy for a couple of years over public network. It worked perfectly before. The users from different LNA can talk to each other over SIP call (xlite or Linksys adapters). We could fax over SIP from other countries. However, fax stopped working shortly (about 6-month). But SIP call worked fine till the beginning of this year. Suddenly, sip-phone only hears ring. There is no sound on both sides. Do anyone have the similar problem or encounter stability issues in this setup (SER + Rtpproxy)? Best Steven

Re: [Serusers] Can SER support MySQL 5.0.22
by roayu 26 Nov '07

26 Nov '07

Hi, I managed to create the mysql.so after re-intall the MySQL, especially the mysql-dev package. Thanks for your help! Roa Yu -----Original Message----- From: SIP [mailto:sip@arcdiv.com] Sent: Monday, November 26, 2007 8:36 PM To: roayu Cc: serusers(a)lists.iptel.org Subject: Re: [Serusers] Can SER support MySQL 5.0.22 First off, do you have the mysql-dev package installed? As for whether or not it will run with mysql 5.0.22, it can, but it's tricky. The makefile for the mysql module doesn't look everywhere for the libmysqlclient libs when it's compiling. It expects the libs to be in a particular place, and if they're not there, it ignores the libpath, compiles ANYway, and they just fails to work once you start up SER. It gives NO errors on compile, which makes it utterly difficult to track down. The latest RPMs for RHEL/CentOS from the MySQL community site place the libmysqlclient.so.X libs into /usr/lib and NOT /usr/lib/mysql as SER expects. SER will simply NOT find it in that location. What we've ended up having to do is symlinking the /usr/lib/libmysqlclient* into /usr/lib/mysql, recompile the mysql module, and install it in the correct place. Then, SER runs happily and readily without weird errors. Also note that there is a patch that must be applied to use MySQL 5.0.X for SER 0.9.6 see http://www.iptel.org/faq/why_does_my_mysql_5_0_x_connection_time_out_when_us ing_ser_0_9_x N. roayu wrote: > > Hi there! > > > > Would like to ask, can SER 0.9.6 support MySQL 5.0.22 ?

[OpenSER-Users] OpenSER Sending INVITE twice
by Douglas Garstang 26 Nov '07

26 Nov '07

I have an OpenSER 1.1 install here, and for some reason, OpenSER is sending the INVITE message twice to the upstream host. The time difference between them is about 1/5 of a second. Nothing is received between the first and second INVITE's. Why is OpenSER doing this? I have xlog() statements everywhere in openser.cfg, and OpenSER is only logging ONE outgoing INVITE message, eventhough it's sending two. It is logging the multiple TRYING messages that come back however. OpenSER is not calling failure_route because nothing is logged in there. What could be going wrong? Why is it doing this?
