Jenkins2 has submitted this change and it was merged. ( https://gerrit.asterisk.org/9148 )
Change subject: res_rtp_asterisk: Allow OpenSSL configured with no-deprecated.
......................................................................
res_rtp_asterisk: Allow OpenSSL configured with no-deprecated.
Furthermore, allow OpenSSL configured with no-dh. Additionally, this change
allows auto-negotiation of the elliptic curve/group for servers, not only with
OpenSSL 1.0.2 but also with OpenSSL 1.1.0 and newer. This enables X25519
(since OpenSSL 1.1.0) and X448 (since OpenSSL 1.1.1) as a side-effect.
