i've try configure TLS and zrtp in freeswitch, but i've problem with TLS,
i've using tutorial from this website wiki.freeswitch about SIP_TLS.
when i activated in my softphone (i'm use phonerlite) it say TLS registered, but there is no sound feedback. i try using echo test by calling 9196 but there is no sound feedback.
but, if i'm use TCP or UDP , there is no problem with that, i can hear voice feedback when try call 9196.
thanks.
