Chapter 5. Setting up a SMS Gateway
Variable
Value
Description
validityperiod
integer
How long the message will be
valid, i.e., how long the SMS
center (the real one, not the
phone acting as one for Kannel)
will try to send the message to
the recipient. Encoded as per the
GSM 03.40 standard, section
9.2.3.12. Default is 167, meaning
24 hours.
retry
boolean
Assuming that kannel is well
configured and we had one
sucessful connection, if retry is
true, kannel will always retry the
connection even if some related
error ocur.
keepalive
seconds
Kannel would "ping" the modem
for this many seconds. If the
probe fails, try to reconnect to it.
my-number
number
Optional phone number.
sms-center
number
SMS Center to send messages.
sim-buffering
boolean
Whether to enable the so-called
"SIM buffering behaviour" of the
GSM module. if assigned a true
value, the module will query the
message storage memory of the
modem and will process and
delete any messages found there.
this does not alter normal
behaviour, but only add the
capability of reading messages
that were stored in the memory
for some reason. The type of
memory to use can be selected
using the ’message-storage’
parameter of the modem
configuration. Polling the
memory is done at the same
interval as keepalive (if set) or 60
seconds (if not set). NOTE: This
behaviour is known to cause
minor or major hicups for a few
buggy modems. Modems known
to work with this setting are
Wavecom WM02/M1200 and the
Siemens M20.
