Thanks Jeff, just to confirm, password are not sent in plain text? I
want to safeguard against man in the middle attacks, sniffing
traffic of clients. <br>
<br>
Thanks, <br>

<div>Hi Motty,</div>

Isn't the whole point of the nonce in a SIP registration to
ensure the secret doesn't go on the wire in plain-text? Is
this not enough, or are you looking to hide the username
too?

<div>Ps, if so then I think TLS is the missing part of
your equation.</div>

I am searching for a solution to encrypt
authentication from Asterisk server to clients.
Searching srtp seem to encrypt traffic, I just want
client authentication with encryption. Can someone
point to the right direction? has anybody used ZRTP?
experience with ZRTP?<br>
<br>
Thanks,<br>

You want SIP over TLS. That encrypts the signalling. SRTP
and ZRTP encrypt the actual voice traffic.<br>

Thanks Jeff, <br>
I don't want SIP over TLS. I would like to encrypt password
only, I suppose over TLS.<br>
<br>
Thanks, <br>

The password isn't sent - SIP auth involves a challenge/response
with hashing (digest authentication). If that's all you are
interested in, you are already there.<br>
