SIP User's Manual 450 Document #: LTRT-65415
MediaPack Series
Parameter Description
Web: Establish Conference Code
EMS: Establish Code
[ConferenceCode]
Defines the digit pattern, which upon detection, generates the
Conference-initiating INVITE when 3-way conferencing is
enabled (Enable3WayConference is set to 1).
The valid range is a 25-character string. The default is “!”
(Hook-Flash).
Web/EMS: Conference ID
[ConferenceID]
Defines the Conference Identification string (up to 16
characters). The default value is 'conf'.
The device uses this identifier in the Conference-initiating
INVITE that is sent to the media server when
Enable3WayConference is set to 1.
For example: ConferenceID = MyConference.
10.12.5.8 Emergency Call Parameters
The emergency call parameters are described in the table below.
Table 10-47: Emergency Call Parameters
Parameter Description
Web/EMS: Emergency
Numbers
[EmergencyNumbers]
Defines a list of “emergency” numbers.
When one of these numbers is dialed, the outgoing INVITE message
includes the SIP Priority and Resource-Priority headers. If the user
places the phone on-hook, the call is not disconnected. Instead, a
Hold Re-INVITE request is sent to the remote party. Only if the
remote party disconnects the call (i.e., a BYE is received) or a timer
expires (set by the EmergencyRegretTimeout parameter) is the call
terminated. This scenario is applicable only to FXS interfaces.
These emergency numbers can also be used for pre-emption of E911
IP-to-Tel calls when there are unavailable (busy) channels. In this
scenario, the device terminates one of the busy channels and sends
the E911 call to this channel. This feature is enabled by setting the
CallPriorityMode parameter to 2 (“Emergency”) and by defining an
emergency number value of “911” for the EmergencyNumbers
parameter. For a description of this feature, see Pre-empting Existing
Call for E911 IP-to-Tel Call. This scenario is applicable to FXS/FXO
interface.
The list can include up to four different numbers, where each number
can be up to four digits long.
Example: EmergencyNumbers = ‘100’,’911’,’112’
Web: Emergency Calls
Regret Timeout
EMS: Emergency Regret
Timeout
[EmergencyRegretTimeout]
Determines the time (in minutes) that the device waits before tearing-
down an emergency call (defined by the parameter
EmergencyNumbers). Until this time expires, an emergency call can
only be disconnected by the remote party, typically, by a Public Safety
Answering Point (PSAP).
The valid range is 1 to 30. The default value is 10.
Note: This parameter is applicable only to FXS interfaces.
