Kannel 1.4.1 SMPP connection problem (bug)

For a while, I had a problem with Kannel where eventually it would stop sending MO for some reason. The messages would not get lost, instead, they started queuing, but they will not sent. Later, I found out the problem. It's only with when the transceiver-mode is set. For example:

group = smsc
smsc = smpp
host = 123.123.123.123
port = 600
transceiver-mode = true
smsc-username = "STT"
smsc-password = foo
system-type = "VMA"
address-range = ""

Apparently, as per Donal Jackson (another Kannel Guru) this error also applies for those SMPP connection that uses the TRX/RX:

group = smsc
smsc = smpp
host = 123.123.123.123
group = smsc
smsc = smpp
host = 123.123.123.123
port = 600
receive-port=1234
smsc-username = "STT"
smsc-password = foo
system-type = "VMA"
address-range = ""

Once again, Sipte Tolj (aka: the messiah of Kannel) helped me with this problem. The way to fix it is to configure a transmitter and receiver and remove the transceiver. The example will be the following:

####TRAX#######
group = smsc
smsc = smpp
host = 123.123.123.123
port = 600
smsc-username = "STT"
smsc-password = foo
system-type = "VMA"
address-range = ""

####RECEIVER#######
group = smsc
smsc = smpp
host = 123.123.123.123
receive-port=2345
smsc-username = "STT"
smsc-password = foo
system-type = "VMA"
address-range = ""
