I've been looking for an answer for my problem with Kannel v1.4.1.
Currently I'm using Siemens MC35i terminal as modem.
For some reason some of my SMS's don't get sent. Problem occurs only
with first message of a bundle of messages. Kannel error message says:
2007-11-27 19:30:49 FAILED Send SMS [SMSC:SIEMENS_MC35i] [SVC:XXX]
[ACT:] [BINF:] [from:XXX] [to:XXX] [flags:-1:0:-1:-1:18] [msg:75:Host As
XXX is DOWN Info: PING CRITICAL -] [udh:0:]

[BINF:] [from:XXXX] [to:XXXX] [flags:-1:-1:-1:-1:16]
[msg:14:NACK/MALFORMED] [udh:0:]
Aarno Syvänen's answer on some forum told that NACK/MALFORMED means
malformed message, but this cannot be true since exactly the same
message is sent to other recipients.
http://www.mail-archive.com/[EMAIL PROTECTED]/msg05916.html -article was
told something about modem not being ready for AT command. I could not
apply the specified patch since the c-file wasn't found on my installation.
This is my kannel.conf:
group = core
admin-port = 13000
admin-password = XXX
status-password = XXX
admin-allow-ip = "127.0.0.1;xx.xx.xx*"
log-file = "/var/log/kannel/kannel.log"
log-level = 3

box-allow-ip = "127.0.0.1;xx.xx.xx.*"

Is there something in my modem's setup that should be changed or is this
a bug in kannel?
I'd really appreciate your help.
