[EmergencyNumbers]
Version 6.4
tone is played to the channel.
Defines the duration (in milliseconds) for which the device waits for
a disconnection from the Tel side after the Blind Transfer Code
(KeyBlindTransfer) has been identified. When this timer expires, a
SIP REFER message is sent toward the IP side. If this parameter is
set to 0, the REFER message is immediately sent.
The valid value range is 0 to 1,000,000. The default is 0.
Enables QSIG transfer for IP-to-Tel and Tel-to-IP calls.

[0] IP2QSIGTransfer = Enables IP-to-QSIG transfer. (default)

[1] QSIG2IPTransfer = Enables QSIG-to-IP transfer.
Defines the maximum duration (timeout) to wait between call Setup
and Facility with Redirecting Number for replacing the calling
number (for Tel-to-IP calls).
The valid value range is 0 to 10,000 msec. The default is 0.
The interworking of the received Setup message to a SIP INVITE is
suspended when this parameter is set to any value greater than 0.
This means that the redirecting number in the Setup message is
not checked. When a subsequent Facility with Call Transfer
Complete/Update is received with a non-empty Redirection
Number, the Calling Number is replaced with the received redirect
number in the sent INVITE message.
If the timeout expires, the device sends the INVITE without
changing the calling number.
Notes:

The suspension of the INVITE message occurs for all calls.

This parameter is applicable to QSIG.
Table A-45: Emergency Call Parameters
Defines a list of "emergency" numbers.
For CAS, and ISDN: These emergency numbers are used for the
preemption of E911 IP-to-Tel calls when there are unavailable or busy
channels. In this scenario, the device terminates one of the busy channels
and sends the emergency call to this channel. This feature is enabled by
setting the CallPriorityMode parameter to 2 ("Emergency"). For a
description of this feature, see ''Pre-empting Existing Call for E911 IP-to-
Tel Call'' on page 274.
The list can include up to four different numbers, where each number can
be up to four digits long.
Example: EmergencyNumbers = '100','911','112'
