[Linphone-users] Security validation problem

[Junk Mail]

I get a message on an android running 4.2.3 authenticating another android 4.2.3. The enclosed shows the exact wording but when I call from the message screen the call never goes through. If I call from my contacts to the same person it works. 

It appears to be trying to authenticate only this user and not the others user.

Thx
