Hello,

 I went over the code. AES128 is the only algorithm that is suppored
 today. More importantly there are some concerns on the vulnerability as
 discussed in
 http://lists.digium.com/pipermail/asterisk-security/2005-August/60.html.
 People are using UDP VPNs to satisfy customer requirements.
 http://lists.digium.com/pipermail/asterisk-users/2005-August/120293.html

we are using plain ipsec here. From softphones, we just use operating
system's native ipsec support. For hardphones, we have a custom device
based on soekris board with vpn hardware encryption accelerator, which
does the job for the phone.


  Juraj.

 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.

There has been a little discussion of this topic on the
asterisk-security list somewhat recently.
You may want to look at the message archive from August (
http://lists.digium.com/pipermail/asterisk-security/2005-August/thread.html

) as well as the one from September.

Hope this offers a little help; as someone mentioned, not much
documentation is out there.
From the August thread:

Basically it's an automatic features (CVS-HEAD only, btw) where anytime
a pair of IAX peers have encryption set to yes (or, as I understand
it, a mutually-agreed-upon and supported algorithm) then it just happens
automagically.

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:
