2.10. OVER THE AIR [ADVANCED]
2.10.2 Via SMS (GSM)
To interact with the unit via SMS messages, a Destination holding the
sender’s Telephone Number has to be defined. As Telephone Number
destinations are also used for voice call authorization/generation the
Destination configuration has to be so that TAIP console access is
granted. See the
XADP
TAIP message for more information.
Once the Destination is correctly configured the unit will respond
with an SMS message to any TAIP command received via a SMS
message from that destination.
When creating the Destination make sure of using the Telephone
Number string that the unit receives from the cellular operator
as generating party. Sometimes the number you use to dial is
not exactly the number that appears on a phone when a SMS is
generated. For example although the generating number is 123456
the cellular operator may tell the unit that the remote party is
+44123456. In this case the long number including the + sign
has to be entered in the unit as Destination or it will fail on
recognizing the valid sender.
Note:
SMS messages can be sent/received even with no GPRS registration
so you can have the unit working on a GSM-only basis too.
SMS messages are great for solving the NAT problem mentioned on
the previous sub-section.
Telephone numbers can also be defined with e-track Configuration
Assistant’ Address Book .
2.10.3 Voice (GSM)
e-track
TM
is capable of receiving phone calls from any numbers or
restrict incoming calls to the numbers on its Destination Points list
(or e-track Configuration Assistant’ Address Book ). The unit may be
set to automatically answer a call or to wait for a user button-press
to answer.
Also, e-track
TM
can generate voice calls automatically
based on an event configuration. These configuration options can be
set with
e-track Configuration Assistant software or they can also be
manually configured via TAIP commands. Refer to the
XAVC
,
XAVE
commands and voice signals for more information.
