OK, so ZRTP is a proposed open standard. Not a program.
Proposed RFP by Phil Zimmerman et al is here:
http://www.zfone.com/docs/ietf/draft-zimmermann-avt-zrtp-23x.html
Phil Zimmerman et al and implement protocol in proprietary program
zphone. Zphone FAQ at makes it clear that zphone is not open
source[1]
Wikipedia indicates there are four purported free implementations[2].
I have not validated that claim. Nor the definition of "free" in that
context. References to "GNU ZRTP" and "libzrtp" are worth pursuing...
