SMS routing based on smsc-id does not work properly.

Dear, Sirs!


I have two different SMSC(one is SMPP-based, another one is HTTP-based ) in configuration file and have some problems with
routing. I want to route reply to the same SMSC, which receive
request. I make configuration as in documentation
http://www.kannel.org/download/kannel-userguide-snapshot/userguide.html#AEN4033
but it does not work properly.

CONFIG:

group = core
admin-port = XXXX
smsbox-port = XXXX
log-file = "kannel.log"
log-level = 0
box-deny-ip = "*.*.*.*"
box-allow-ip = "127.0.0.1"
access-log = "access.log"
store-file = "kannel.store"


# SMSC CONNECTIONS

group = smsc
smsc = smpp
smsc-id = SMSC1
denied-smsc-id = SMSC2
transceiver-mode = 1
host = SMPP SMSC IP Addr
port = XXXX
smsc-username = "user"
smsc-password = "pass"
system-type = "VMA"


group = smsc
smsc = http
smsc-id = SMSC2
denied-smsc-id = SMSC1
system-type = kannel
smsc-username = "user"
smsc-password = "pass"
port = XXXX
send-url = "http://XXX.XXX.XX/sms"
connect-allow-ip = "HTTP SMSC IP"


# SMSBOX SETUP

group = smsbox
bearerbox-host = localhost
sendsms-chars = "0123456789 +-"
log-file = "smsbox.log"
log-level = 0
access-log = "access.log"

group = sms-service
keyword = default
name = "test1"
max-messages = 10
concatenation = false
allowed-receiver-prefix = 1111
accepted-smsc = SMSC1
split-chars = " "
omit-empty = true
text = "TEST1"

group = sms-service
keyword = default
name = "test2"
max-messages = 10
concatenation = false
allowed-receiver-prefix = 2222
accepted-smsc = SMSC2
split-chars = " "
omit-empty = true
text = "TEST2"

If I send sms request from SMSC1, kannel send reply back via SMSC2, but if i send
sms request from SMSC2, kannel sends reply back via SMSC2 too.
Then i set config block of SMSC2 above SMSC1. And if I send sms
request from SMSC1, kannel sends reply back via SMSC1, but if i send
sms request from SMSC2 kannel send reply back via SMSC1 too.

Only if i set routing based on "allowed-prefix" in my config, then all
work fine. But kannel users guide shows than i can do routing based on
"smsc-id, denied-smsc-id, accepted-smsc" params.

What i do wrong?

Thank you beforehand.
