Hi
I'm interested in getting Linphone enabled with ZRTP connected to a FreeSWITCH server.
Everything seems to build okay but the ZRTP connection is never successfully established.
There a few threads on this subject from about a year ago which seems to indicate that FS requires that the optional 'zrtp-hash' to determine if both clients supports ZRTP. A patch was also made available for Linphone but were never integrated into the main branch. The patch now looks incompatible with the latest releases of Linphone.
