Re: Kannel - incoming SMS is not detected but outgoing works fine

in the smsc group add the following lines:

sim-buffering = true
keepalive = 5

so your smsc configs would look like this:

group = smsc
smsc = at
modemtype = auto
device = /dev/ttyACM0
my-number = "+264722222111"
port = 10000
connect-allow-ip = 127.0.0.1
log-level = 0
sms-center="+264722500029"
sim-buffering = true
keepalive = 5
