hello
I have to say thank you for this great job.
I installed sms server tools smstools3-3.1.6 and it work fine .
I use it for alarm handler by its voice call for sending missed calls for cost consumption but some times it show me NO CARRIER how can I handle it or how can I config it for example the sms server tries for n times if it receives no carrier or busy or ....
this is my log of of what I explained :

2010-04-19 11:38:46,6, GSM1: Moved file /var/spool/sms/checked/sms_12718 to /var/spool/sms/sent/sms_12718


and this is my config file:

devices = GSM1
outgoing = /var/spool/sms/outgoing
incoming = /var/spool/sms/incoming
sent = /var/spool/sms/sent
logfile = /var/log/smsd.log
loglevel = 8
failed = /var/spool/sms/failed
voicecall_hangup_ath = yes
[GSM1]
device = /dev/ttyS0
incoming = no
baudrate = 115200
rtscts = no

There is no built-in option for retrying.

After a voice call has ended, you could check from the sent message file what was the result. In this case it should be Result: NO CARRIER, and you can move the file back to the outgoing directory.

thanks a lot
