[Linphone-developers] Linphone Android v1.2.1 made silent call

[Coca]

Dear all,

I am an old fan of Linphone and I use it communicate with my friends.

Recently when we update to Linphone Android v1.2.1 on market ( or built it from latest GIT),

we noticed that Linphone running on two Android mobile phone will establish a silent call, 

while either of them can establish a normal with a iphone version for Linphone.

Does anyone else have this situation?
