the routing group programmed in the system.
• The destination port to route the call is determined as per the
member selection method assigned to the routing group. The
destination port can be BRI Port or Mobile.
• If the destination port, to route the call is found to be GSM, the
GSM port will send the number to the GSM module for dialing out,
even if the port is True or False.
• The system doesn't check the Allowed and Denied Lists or
automatic Number Translation, for dialing the emergency number,
but the port must be enabled.
Emergency dialing in GSM network is explained in detail as below:
• A Mobile station has two intelligent systems within itself viz. the
GSM Engine and the SIM card.
• Both, the GSM engine and the SIM card classify few number
strings as Emergency numbers. Such numbers are dialed by the
module with a specific SET UP message known as Emergency Call
Set Up message.
• These numbers are dialed by the GSM Engine in following cases:
• Not registered with subscribed Service Providers' Network. In
such case, the Engine dials the Emergency number using any
other available GSM network.
• When SIM is absent.
• When SIM is invalid (Only few Emergency numbers are
allowed. This depends on the GSM Engine).
• When SIM is blocked.
• When wrong SIM PIN is entered.
• For example, for a specific GSM Engine and a SIM Card from a
Service Provider, following sequence is followed to dial an
Emergency Number:
• It will first search for emergency call number stored in the SIM
phone book. If there is at least one emergency number in the
SIM, it will search for the number. If does not match, it will search
for 112 or 911.
• If SIM does not have any emergency number stored it will search
for the number in the default emergency number list stored in the
firmware which are 000, 08, 112, 110, 911, 999.
• If the SIM is invalid means either PUK1 Blocked or PUK2 Blocked
or No SIM, it will search for emergency numbers, which are 000,
08, 112, 110, 911, 999, 118 and 119.
