Hi,

Does Asterisk support encryption of voice traffic? I found following wiki
that describes IAX RSA authentication. I was able to implement the
public/private key authentication among three Asterisk servers connected
using IAX protocol. I am not certain if voice traffic can also be encrypted
among the Asterisk servers. Your help is highly appreciated.

Thanks in advance

Scott:

The only secure encryption scenario is one that covers
point-to-point.  In that case, Asterisk has little or nothing
to do: all the [en|de]crypting work is done by the SIP phones
at the ends.

I have been investigating the issue, and AFAIK the only phone
that support secure communications in the Sipura.

In addition to a pair of phones, you will need the appropriate
keys, which are nicely provided by Voxilla:
