Hi, I m a new FS user. I am trying to use FS with TLS as a SIP server. My client application is CSipSimple. According to my tests, FS do not need to verify itself to client or do not verify clients' certificates. Maybe there are some problems at the client side but i thought it is not. But I m also open for new, fresh ideas about FS-CSipSimple configuretions. I read wiki and some mail-group posts. There is a paramater "tls-verify-policy". If I didn't understand wrong, I must set it with "all" value in sofia.conf.xml. I m not sure that if I set it true or wrong. Also not sure about the syntax of sofia.conf.xml file. Can anyone tell me what is the correct syntax for sofia config file for adding a new parameter. Or if I am wrong, please, tell me the correct solution. Thank you for all. Best regards, Burak
