[asterisk-users] SIP over SSL TCP or SRTP?

[Bruce B]

Thanks. Want to secure everything and anything possible.

1- Can both  SIP over TLS  and SRTP work in conjunction to each other?
2- Is SIP over TLS a package or added on module that can be installed from
Digium Asterisk repository?
3- SRTP takes care of the RTP and makes it secure so that MITM type
sniffing is not possible?

Regards,
