Hello,
Most phones these days support SRTP/TLS and is not a bad idea to have better security if possible. On the other hand most Trunks/Upstream dont support SRTP. So freeswitch has to manage the following three scenarios,
1. Internal calls: client ----SRTP--- FREESWITCH-----SRTP-----client
2. External calls incoming: External trunk ----RTP----FREESWITCH-----SRTP----client
3. External calls outgoing: client----SRTP----FREESWITCH-----RTP----External trunk
This is a very common scenario. Can somebody give a tip how to do 2 and 3?
For 3 one can put in dial plan rtp_secure_media=off in the dial plan. However, I am not sure how to do 2.
Thoughts?
