Hi,

I just wonder if a communication is really secure ?

I mean, suppose that 2 peoplse connected to their own ASTERISK server,
and 2 users are connected to this server...

What do you think about the link between the phone and the server ?
(Usually using SIP protocol)
- Is that easy to intercept communications ?
- Is there a way to encrypt SIP communications ? if so, how can we do that ?

Thanks

Stephane
