Call Forwarding
How it works
When a button is pressed, say Button 1, The DMG1 will scan the SIM card for the name that begins
with 1A and call the number stored there. The call will ring until the call forward timer runs out. The
call is then automatically dropped and a new call set up to the Number stored at 1B. If there is no
number stored at 1B the DMG1 will call the number at 1A again. This will ring until the call is
answered or the DMG1 countdown timer runs out or in some cases the Network drops the call anyway.
This will be about 30 seconds. As network conditions are variable the number of rings for the first
number may vary a little over time.
Modifying the Settings.
The Call forward timer defaults to 1 second that is to say it is effectively disabled. The call duration
timer is 30 seconds. Both of these can be changed.
Usage suggestions
o
With a single Number stored at 1A and no 1B the system will redial the number at 1A as is stated
above. If the call forward timer is set to about 15 seconds the effect is to give a 4 or 5 rings
followed by a short break when the phone will start ringing again. Many users find this provides a
form of distinctive ringing thus indicating a call from the gate. It can be useful to reduce the call
forwarding timer (to about 8 Seconds) to make the first ring only one or two.
o
The call forwarding timer may be extended to any value up to 99 seconds if needed but it must
be noted that the default value was chosen to avoid the likelihood of a customers Voicemail
answering the call in which case the Second call will not occur.
o
The call duration timer can also be increased from its default of 30 seconds up to 99 seconds if
more time is needed to answer the phone, perhaps for a landline in a large building. The 30
second default was chosen to keep call charges at a minimum as the call will not necessarily drop
if the remote number is a mobile when the remote party hangs up.
Changing the settings
If you want to change the timers you can do so by storing a name on the SIM card in the form
DAT4xxyy where xx or yy is a number of seconds. The value for xx is the time delay from the call
setup to the call forward trigger. The value for yy is the call duration timer and is optional. It is best
to store a dummy telephone number, say 1234 as some phones will not write a name to the SIM
properly without one and the DMG1 will be unable to read the call forwarding information.
Note
: If you want to make the call forward less that 10 seconds you must enter a leading zero eg 07
for 7 seconds. Entering a value of less than 30 seconds for the call duration will not have any effect.
DAT must be in Capitals.
