I dont know any gateways with SRTP support. Which does not mean they dont exist :)
- can cisco 2650MX handle traffic from 24 simultaneous calls G711 ?
- Can SAME cisco get those calls via T1 and then forward via SIP ?
Ask your friendly Cisco support :)

Wrong list for that :) I know

There are clients. See my previous mail. SRTP is completely transparent for SIP proxies.
Anyway IPSec seems a good solution, but if I configure the proxy server
for
IPSec, can i handle both encrypted and not encrypted calls?
You should be able to receive messages encrypted over IPSec as well as the plain old messages. But this solution will only work if you put an IPSec gateway in front of a complete subnetwork with phones in it or use only soft-phones. Because I do not know any hard phones which support IPSec (correct me if I'm wrong).

You want to encrypt the signaling, media or everything?
For everything I guess IPsec is the solution, for signaling only, TLS can be an alternative to IPsec. Just for media, a solution would be Secure-RTP but I am not aware of any client implementing it.
If the signaling is encrypted, the proxy must know how to decrypt it.

Hi all,
i have a question:
-do you know how it's possible to encrypt the comunication between two
SIP
client?
-does the proxy implement some particular tasks or actions, or is it a
client-side
problem?
-if it is so, do you know any SIP client that implements encription?
Thank you very much stefano
