Parameter Description
Play Busy Tone to Tel
[PlayBusyTone2ISDN]
Enables the device to play a busy or reorder tone to the PSTN after a Tel-
to-IP call is released.
 [0] Don't Play = Immediately sends an ISDN Disconnect message
(default).
 [1] Play when Disconnecting = Sends an ISDN Disconnect message
with PI = 8 and plays a busy or reorder tone to the PSTN (depending on
the release cause).
 [2] Play before Disconnect = Delays the sending of an ISDN Disconnect
message for a user-defined time (configured by the
TimeForReorderTone parameter) and plays a busy or reorder tone to
the PSTN. Applicable only if the call is released from the IP [Busy Here
(486) or Not Found (404)] before it reaches the Connect state;
otherwise, the Disconnect message is sent immediately and no tones
are played.
Subject
[SIPSubject]
Defines the value of the Subject header in outgoing INVITE messages. If
not specified, the Subject header isn't included (default).
The maximum length is up to 50 characters.
Multiple Packetization
Time Format
[MultiPtimeFormat]
Determines whether the 'mptime' attribute is included in the outgoing SDP.
 [0] None = Disabled (default)
 [1] PacketCable = includes the 'mptime' attribute in the outgoing SDP --
PacketCable-defined format
The 'mptime' attribute enables the device to define a separate
Packetization period for each negotiated coder in the SDP. The 'mptime'
attribute is only included if this parameter is enabled, even if the remote
side includes it in the SDP offer. Upon receipt, each coder receives its
'ptime' value in the following precedence: from 'mptime' attribute, from
'ptime' attribute, and then from default value.
Enable Reason Header
[EnableReasonHeader]
Enables / disables the usage of the SIP Reason header.
 [0] Disable.
 [1] Enable (default).
Enable Semi-Attended
Transfer
[EnableSemiAttendedTr
ansfer]
Determines the device behavior when Transfer is initiated while in Alerting
state.
 [0] Disable = Send REFER with Replaces (default).
 [1] Enable = Send CANCEL, and after a 487 response is received,
send REFER without Replaces.
3xx Behavior
[3xxBehavior]
Determines the device's behavior regarding call identifiers when a 3xx
response is received for an outgoing INVITE request. The device can
either use the same call identifiers (Call-ID, Branch, To, and From tags) or
change them in the new initiated INVITE.
 [0] Forward = Use different call identifiers for a redirected INVITE
message (default).
 [1] Redirect = Use the same call identifiers.
