Hi,

We are currently have Now SMS/MMS Gateway (v2008.06.03) it's being working fine until a few days ago. The problem we have is that we have HIGH OutBound SMS QUEUE'd messages over 24,000.
When we noticed the problem the application was displaying the error "SMPP Failure - Unable to login to SMPP Server with specified parameters" Error Timeout waiting for response from server, we managed to fix SMPP by changing the port user/pass, and the error disappear.
However, since that problem notifications are not being deliver to the mobiles, if you try to send a MMS, the MMS is received by the application process, even it sends the notification to SMPP server, but the user never receive the notification, the same thing happends with email to sms. (Note. the NowSMS is not being used as SMPP server) we have another server doing that job.

I wonder if can guide me based on your experience, what would be the reason of this behave.

note: there's no firewalls or nowsms changes during long time ago (because we also admin the firewalls).

Attached i included the statistics of the application. after flushing a lot the Q directory we still seeing the queque value growing up.

Hi Felix,

Did you recently update the NowSMS license installed on that system?

The old version of NowSMS (2008) that you are running does not understand the new license code that has been installed, and it is transmitting messages very slowly.

There are two solutions:

1.) Update the NowSMS version.

We just posted a new release yesterday. It can be downloaded at http://www.nowsms.com/download/nowsms20110705.zip (additional details can be found at http://www.nowsms.com/nowsms-update).

If you are hesitant to install a brand new release, I would recommend the 2010.11.26 version, which is installed at numerous MMSC installations, and has proven to be a very stable release. It can be downloaded at http://www.nowsms.com/download/nowsms20101126.zip.

2.) Alternatively, if you do not wish to update at this time, please send a copy of your license key to nowsms@nowsms.com with "Attention: Des" in the subject line, and I will send back a license key that will resolve this problem.

Hi Felix,

What MSISDNHeader related settings do you have in MMSC.INI?

Does this affect person-to-person MMS?

Or is it only affecting e-mail to SMS/MMS?

Could I see some examples from the MMSC-yyyymmdd.LOG file?

If you need to send any information that should not be posted publicly, please send to nowsms@nowsms.com with Attention: Des in the subject line. (Also post a reply here so that I know to look for the e-mail.)

Hi Felix,

Your e-mail was helpful in helping me understand your configuration, and that it is e-mail to SMS/MMS that is an issue. Specifically sending an e-mail to number does not work, but sending an e-mail to +number does.

If this worked previously, then something must have been different previously with the SMPP connection. (You mentioned before that you had to change a port number and/or username/password because of connection failures.)

If the MMSC is properly configured (yours appears to be), then SMS messages (MMS notifications) generated by the MMSC will always be addressed to a number that has been internationalized, such as +50799999999.

So I don’t think you need to worry about that.

The way the SMS engine of NowSMS works is that if an SMS message is addressed to an international number (starts with +), then it sets the SMPP TON to 1, meaning international.

If the number does not start with a +, it sets the SMPP TON to 0, meaning unknown ... or that the SMSC should use its rules to determine the number type.

You can go into the properties of the SMPP connection in NowSMS and under “Advanced Settings”, force the destination TON setting to 1. That would immediately resolve this issue, but could cause some problems if you also need to send some messages in a national number format such as 0999999999. (The MMSC should internationalize the number before it sends, but if you have any other applications it could be an issue.)

An alternative was just added in the most recent version of NowSMS (2011.07.05). NowSMS now supports number prefix conversions when sending SMS. Edit SMSGW.INI, and locate the section header for your SMPP server, such as [SMPP - server:port]. Under that header, add OutRecipPrefixConvert=507:+507 ... this will cause NowSMS to transform 50799999999 to +50799999999 before it tries to send an SMS out that connection.
