Dear Sir,

When I send MMS via NowSMS Web Interface, I can receive the MMS successfully.
When I use API, I receive following error in the log:
2015-05-06 00:00:15,SAR-<MSISDN>-92-2-1,LocalSystem,<MSISDN>,Retry Pending - HTTPSMSC: Connection failed, HTTP status code = 503. -- NowSMSModem - 192.168.1.100:8990,SubmitUser=<USERNAME>;SMSCRouteName=192.168.1.X

Besides, why I submitted MMS but it seems like sent via SMS method?

Hi,

It looks like your system is setup to send MMS as an MMSC, instead of sending via the operator MMSC.

How many modems do you have connected?

The first thing I would do is delete the outbound SMS message queue. Because, it is so large, the quickest way to do this is to delete the Q subdirectory that is in the NowSMS directory.

In the SMSC list, select your modem and press "Properties" ... make sure that "Support any outbound message traffic" is enabled.

That should fix the problem.

If for some reason, the problem persists, go to the "MMSC Routing" page and select your modem as the "Default Route". This last step should not be necessary, but maybe there is a configuration issue related to using IPaddress:port for the modem instead of selecting the modem by name. I will run some tests.

Follow-up...

I ran a test of a fresh install, and there is a configuration problem that occurs if you define a modem connection using the IPaddress:port format. The settings for sending MMS do not get set correctly, and lead to the problem you are seeing.

While my second suggestion above will work, after testing this, I would suggest an alternate solution.

Delete the modem from the SMSC list.

Add it back, but do not include the port number (:8990 will be assumed by default), or select the modem by name from the list.

To be clear, if defining the modem by IP address, enter 192.168.1.100 instead of 192.168.1.100:8990. This will allow the configuration settings to be applied correctly.

Because it is sometimes necessary to use non-default ports, we will correct this in the next update.
