Hello everyone,

I am trying to set up srtp on my yealink.

I have enabled TLS on the 5061.

When I change yealink_srtp_encryption to 1 (optional) and try to make a call I get the error: Not acceptable here!

So if I understand correctly, I do have srtp enabled on the yealink, but not on fusion pbx.

I tried adding: sip_secure_media to true
in variables, but it doesn't work.

Anyone got the solution?
THANKS
