Re: [Linphone-users] ZRTP on Android

[Daniel Muller]

Thanks I will keep doing only the make now on..

Yes, the peer is a twinkle on which I made ZRTP calls successfully before with a windows build of linphone.

I will try this evening or some of the next ones with another linphone, just in case.. But, well, if twinkle worked with one, it could work with other.

Hi,

First, note that you should do "make" to build the application and not
run prepare_sources.sh yourself anymore.


What you see on the traces is that your phone tries to initiate a ZRTP dialog.
However it gets no answer for the peer and thus ZRTP fails.


Do you have ZRTP enabled on peer?
