[asterisk-security] Asterisk with SRTP and SIP over TLS

[Alejandro Cabrera Obed]

Dear all, I want to know if anybody has implemented an Asterisk server
(1.4 or 1.6) with SRTP and SIP with TLS, in order to encrypt both
signaling and voice packets.

Does it really work ??

And in the affirmative case, does encryption increase the delay and
maybe the voice quality becomes bad ???

Because I see this encryption methods are the more supported in the
hardware IP phones.

Thanks a lot.
