RTMFPTURNProxy is set in your mms.cfg file. it is a system-wide setting for Flash Player. you may set this Flash Player configuration variable to a hostname or IP address of a TURN proxy server (not a URI).
Flash Player supports IETF BEHAVE TURN draft 8, which is now quite dated.
I don't know where is the mms.cfg file.Can u tell me?
anyway, i don't think that let the users to modify the config file is a good thing
Can we just write TURN Proxy address in the Flex ??

no. configuration of a TURN proxy is expected to be site/installation specific and would be configured by your site's system administrator/IT department.
