Dear All, I know that FreeSWITCH supports ZRTP but I would like to know if someone already tried to deploy SRTP on FreeSWITCH? If so, can I have the HOWTO describing this setup if any have been done? Thank you! Serge. _________________________________________________________________ The New Busy is not the old busy.

I tried it, but it exposed bugs in OpenSSL. Soon thereafter, ZRTP became available so I switched to that. If you want SRTP, you have to turn on TLS, make sure that both ends are using it, and enable SRTP in the SIP profile, if I remember correctly. ZRTP is better in my opinion; the only reason why you would want to use SRTP is for interoperability with end-points that support it, but not ZRTP - unless you have a public-key infrastructure in place that you want to use for some reason.
hello Jason, Thank you for your prompt responses and you have been very helpfull. I also tried SRTP on Asterisk and I got virus when downloading libraries ... and I also found ZRTP is better. However, can you be specific about SRTP interoperability with end-points that support it? it looks like this is a benefit of SRTP over ZRTP? While ZRTP is based on SRTP right? Thank you! Serge.

I can see that you are looking for some more information on how strp and zrtp work. I have found quite a bit of information on this topic at the following url: http://www.google.com/search?q=srtp+zrtp Mike On Apr 7, 2010, at 2:00 AM, SERGE TUMBA wrote:
