[Freeswitch-users] Passwords in clear text

Certainly offering support for hashed passwords has benefits and as you
mentioned can be done using something other than the flat file XML directory
format and decoding on the fly.   I think one reason it hasn't been looked
at as a major issue yet is voicemail and conference passwords are generally
only numbers so they can be dialed over a phone, even an 8 digit password is
10^8 combination which is not a whole lot of hashes to brute force, so
compromising even one way passwords would not be a major feat.   It may
deter a compromised machine from giving up its secrets but it certainly is a
very narrow frame of protection.
