Parameter
Mediant 800 Gateway & E-SBC | User's Manual
Description
Note: The parameter is applicable only to digital
interfaces.
Defines the maximum interval within which the PSAP
can use the ELIN to call back the E9-1-1 caller. This
interval starts from when the initial call established
with the PSAP is terminated.
The valid range is 1 to 60 (minutes). The default is 30.
Note: The parameter is applicable only to digital
interfaces.
Enables the device to send a SIP 503 "Service
Unavailable" response if an emergency call cannot be
established (i.e., rejected). This can occur, for
example, due to the PSTN (for example, the
destination is busy or not found) or ELIN Gateway (for
example, lack of resources or an internal error).
■ [0] Disable (default)
■ [1] Enable
Note: The parameter is applicable only to digital
interfaces.
Global parameter enabling the support for the E911
DID protocol, according to the Bellcore GR-350-CORE
standard.
You can also configure the feature per specific calls,
using Tel Profiles. For a detailed description of the
parameter and for configuring the feature in the Tel
Profiles table, see Configuring Tel
Note: If the feature is configured for a specific Tel
Profile, the settings of the global parameter is ignored
for calls associated with the Tel Profile.
Defines a list of "emergency" numbers.
FXS interfaces: 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.
