If 0 and reg.x.serverFeatureControl.dnd is set to 1, the phone will not perform local DND call behavior. If

If 1, the registration includes a secure media stream description along with the usual non-secure media description

secure media stream is included in SDP of a SIP invite.
reg.x.srtp.require
1
0 or 1
0
If 0, secure media streams are not required. If 1, the registration is allowed to use only secure media streams. Any
offered SIP INVITEs must include a secure media description in the SDP or the call will be rejected. For outgoing
calls, only a secure media stream description is included in the SDP of the SIP INVITE, meaning that the nonsecure
media description is not included. If this parameter set to 1, reg.x.srtp.offer will also be set to 1, regardless
of the value in the configuration file.
