Web/EMS: PRACK Mode
[PrackMode]
Determines the PRACK (Provisional Acknowledgment) mechanism
mode for SIP 1xx reliable responses.
[0] Disable
[1] Supported (default)
[2] Required
Notes:
The Supported and Required headers contain the '100rel' tag.
The device sends PRACK messages if 180/183 responses are
received with '100rel' in the Supported or Required headers.
Web/EMS: Enable Early
Media
[EnableEarlyMedia]
Enables the Early Media feature.
Enables the device to send a 183 Session Progress response with SDP
instead of a 180 Ringing, allowing the media stream to be established
prior to the answering of the call.
[0] Disable (default)
[1] Enable
Notes:
To send a 183 response, you must also set the parameter
ProgressIndicator2IP to 1. If it is equal to 0, 180 Ringing response is
sent.
This feature can also be configured as an IP Profile and/or Tel
Profile.
Web: 183 Message
Behavior
EMS: SIP 183 Behaviour
[SIP183Behaviour]
Defines the response of the device upon receipt of a SIP 183 response.
[0] Progress = (Default) A 183 response (without SDP) does not
cause the device to play a ringback tone.
[1] Alert = 183 response is handled by the device as if a 180 Ringing
response is received, and the device plays a ringback tone.
Web: Session-Expires
Time
EMS: Sip Session Expires
[SIPSessionExpires]
Defines the numerical value sent in the Session-Expires header in the
first INVITE request or response (if the call is answered).
The valid range is 1 to 86,400 sec. The default is 0 (i.e., the Session-
Expires header is disabled).
