[Freeswitch-users] SSL/SRTP VS SSL/ZRTP

[Daniel Ivanov]

Well, follow the debug log and you shall see that srtp takes precedence
over zrtp in negotiation and zrtp becomes disabled if srtp is configured
and enabled. Work with the secure_media var in either dialplan or profiles.
I don't remember what the vars for zrtp were, but a search in the wiki will
help you with.that.
