[Freeswitch-users] Way to figure out all possible prams/values for mod_sofia for example

Hi, is there a way to figure out all possible params and their possible values and their types for any given mod? We are working on an interface which will control all possible config params for FreeSWITCH. We are currently going through the source to know what possible values for each param. For example, caller-id-type have possible values of rpid, pid and none. dtmf-type may have rfc2833, info or none. These two prams are fixed params, and anything else as their value than the one mentioned will not work. This is just an example. Thanks, Muhammad
