Hi, I've got some problems. When I use the simple ser.cfg, everything is fine, the ser starts, I can call to other users and I can try to add other users. When I want to change and try to use MySQL, nothing goes. I always receive: Starting SER : PID file /var/run/ser.pid does not exist -- SER start failed I've tryed to touch it but nothing. I've installed the libmysqlclient; I've rebuilt the acc.so according other solutions I saw in this ml... Using the command ser -c it reply that the cfg is ok. Same thing if I try to setup to use it with PSTN What can I do??? I've got to add users, allow them to call to PSTN and accounting the calls... PLEASE HELP!!! Best Regards -- .:FaberK:.
