Hi all,
I am currently using Kannel to send SMS messages from a web application. I have
noticed a problem with SMS messages not getting delivered to two test phones I
have. Typically the message is only received on the first phone I send to, on
about four out of every five times I test. Some testers have also sent larger
batches of messages (10+) and have noticed that usually three or four never
arrive at the phones. I am aware that sms is normally only best effort delivery
anyhow, but messages are going missing in almost every batch I send.
The messages are sent to kannel as seperate http requests, one after the other,
the http requests themselves being constructed and sent in a loop using Java
code. (I also tried to get a message to more than one phone in a single http
request; someone was kind enough to supply instructions for this but I could
not get it working reliably- please see attached. Following those instructions,
I only received all the messages expected about one out every five tests).
I check my application logs and smsbox.log each time, and it appears that all
messages are being received by and forwarded from kannel to the configured
smsc. The log-level configuration is set to 0, which according to the user
guide is the most detailed level...
I therefore requested some UCP trace from the smsc itself, but we never see all
the OT51 requests. Typically if we test with two http requests to kannel, we
will see only the one OT51 (I believe is the request to send an sms message).
I have double checked and triple checked my configuration files, but I am out
of ideas for what could be causing this... Please see attached kannel.conf....
I know it is most likely something wrong with the kannel configuration, so I
would like to know if anyone has experienced this problem with intermittent
delivery before, and what they did about it.
Thanks v much for your help,
Karen

-my previous post on related matter...
Hi Karen, You should add %20 - url encoded space only , the + is another way
tocode space.So your url should be:
http://localhost:13013/cgi-bin/sendsms?username=fake&password=fakeword&to=00447775704910%2000447708821845&text=Hello+world+&from=buddy
Check the sendsms-chars parameter value in the smsbox group if you can sendthe
space character as a part of the to field. If it's not defined itwill accept
thefollowing characters "0123456789 +-" which is the default value. Cheers,
Jovan
