[Freeswitch-users] Configure SRTP and ZRTP on FusionPBX

[Ronggo Kinantoputro]

Hi Brian,

So is it still secure (the call with ZRTP activated on both end point)? Let
say if I try to sniff/capture the Voip Call (with ZRTP enabled) using
wireshark or cain tools, does those tools can listening to the Voip
conversations?

Thanks.
