Hello,<br><br>I investigated the problem putting my OpenSER in debug mode and it occurs that the problem does not exist when OpenSER is launched with "fork=no" instead of "fork=yes".<br><br>Though, I will try to have a closer look at my
openser.cfg file and try to set up your solution as it appears that I have a transaction problem with the presence module as well.<br><br>Thank you very much for your help,<br><br>Antoine<br><br><br>
