sec.srtp.require
If 0, secure media streams are not required. If 1, the phone is only allowed to use 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 non-
secure media description is not included. If this parameter set to 1, sec.srtp.offer will also be set to 1,
regardless of the value in the configuration file.
sec.srtp.requireMatchingTag
If 0, the tag values in the crypto parameter in an SDP answer are ignored. If 1, the tag values must match.
sec.srtp.sessionParams.noAuth.offer
If 0, authentication of RTP is offered. If 1, no authentication of RTP is offered; a session description that includes
the UNAUTHENTICATED_SRTP session parameter is sent when initiating a call.
sec.srtp.sessionParams.noAuth.require
If 0, authentication of RTP is required. If 1, no authentication of RTP is required; a call placed to a phone
configured with this parameter must offer the UNAUTHENTICATED_SRTP session parameter in its SDP. If this
parameter is set to 1, sec.srtp.sessionParams.noAuth.offer will also be set to 1, regardless of the value
in the configuration file.
sec.srtp.sessionParams.noEncrypRTCP.offer
If 0, encryption of RTCP is offered. If 1, no encryption of RTCP is offered; a session description that includes the
UNENCRYPTED_SRTCP session parameter is sent when initiating a call.
sec.srtp.sessionParams.noEncrypRTCP.require
If set to 0, encryption of RTCP is required. If set to 1, no encryption of RTCP is required; a call placed to a phone
configured with noAuth.require must offer the UNENCRYPTED_SRTCP session parameter in its SDP. If this
parameter is set to 1, sec.srtp.sessionParams.noEncryptRTCP.offer will also be set to 1, regardless of
the value in the configuration file.
sec.srtp.sessionParams.noEncrypRTP.offer
If 0, encryption of RTP is offered. If 1, no encryption of RTP is offered; a session description that includes the
UNENCRYPTED_SRTP session parameter is sent when initiating a call.
sec.srtp.sessionParams.noEncrypRTP.require
If 0, encryption of RTP is required. If 1, no encryption of RTP is required. A call placed to a phone configured with
noAuth.require must offer the UNENCRYPTED_SRTP session parameter in its SDP. If set to 1,
sec.srtp.sessionParams.noEncryptRTP.offer will also be set to 1, regardless of the value in the configuration file.
