Re: [Linphone-developers] Port to libeXosip v4

[Guillaume Beraudo]

Hi Eli,

An extract from out official communication of this month:

ZRTP now available on Linphone under proprietary license

Belledonne Communications has developed its own implementation of ZRTP
called "b-zrtp". In addition to the GPL license and unlike the previous
zrtp implementation, b-zrtp is also now available under proprietary
license and does not have any dependencies on OpenSSL. This
new ZRTP implementation uses the cryptography functions of polarSSL
which was already integrated in Linphone.
