Is there another? Problem 2) SEMS module and SER Status My ser and (radius+mysql) are on two separate servers. It's necessary to install mysql also on ser server for know ser-status? HOW i can call this procedure modparam("voicemail", "db_url","sql://ser:heslo@dbhost/ser") in sems configuration file, if mysq is not installed on ser server? (sems is installed with ser on the same server) Please help me !
