SRTP is a client feature. It is indpendent of the SIP proxy. But be
aware how the key for media encryption is transported. If it is
available in the SDP in plaintext (like SNOM phones) you should use TLS
otherwise the everbody can decrypt it who sniffed the INVITE.

Hi,
I'm a newbie in OpenSER usage and in SIP in general so perhaps it's very
simple questions.
I understand that TLS can be activated/disactivated from the configuration
file but can not be used only according SIP number for example or call
streams(internet), that's right ?
What about SRTP ? In order to have SRTP working, I think I "just" need
device phone/softphone with this feature. It's not dependant of the OpenSER
configuration, is it ? Is it possible to force the use of SRTP when it's
possible ? For this, perhaps, I need to configure "mediaproxy" or
"rtpproxy"
module or something else ( mediaproxy daemon for example) ?
Thanks,
Christophe.
