Hello,

I have read dozens of posts and performed countless searches but still have not found an answer.

I have a Cingular SE W810i connected via USB to a machine running NowSMS. Using this interface, I am able to send/receive sms messages to user on Cingular and Verizon users.

Using this interface I am also able to send MMS to Cingular users, but when I try to send MMS messages to Verizon users, messages do not arrive on the Verizon handsets. I am able to manually send an MMS from the SE W810i to a verizon user without a problem.

Does anyone know what may be the problem?

Thanks in advance.

Hi Juan,

That is bizarre.

What version of NowSMS are you using?

The reason I ask is because, if I recall correctly, prior to the NowSMS 2006 release, NowSMS did not, by default, include a SMIL file within the MMS message when a message is submitted via the web interface. It would not surprise me if the US MMS interconnect choked on messages without a SMIL file.

If you're running NowSMS 2006, then I'd be curious if you have tried text only messages, messages with only a single small image, to determine if it is something about certain messages that are preventing them from passing through the interconnect.

Malcolm,

I am using 2006.10.31

I had tried both a text only MMS and an MMS with a small image only both without any success.

Any clues would be greatly appreciated.

Hi Juan,

It is difficult to imagine what the problem could be.

The only explanation would be that there must be something about the structure of the message that is preventing it from going through the interoperator MMS gateway.

The question is, what could it be?

Malcolm's thought about the SMIL file was a good idea, but since you're using a newer version of NowSMS, it is not possible for this to be an issue.

Another thought that comes to mind would be to make sure in your "MMSC Routing" definition where you have the MM1 connection defined, make sure that "Default Sender Address" is blank, and that "Allow Sender Address Override" is NOT checked.

Beyond that ...

I've been looking over raw MMS message files as generated by a variety of different MMS clients, and I notice one minor difference in the binary MMS structure created by NowSMS via the web interface and most other MMS clients.

Let's try this.

Edit SMSGW.INI, and under the [SMSGW] header, add:

MMSCOMPParameters=-cutf-8

This parameter has a side effect that will cause MMS messages generated by the web interface to include an extra attribute within the binary MMS message, which is normally left out.

Let's see if including that parameter makes a difference.

If not, we'll have to try to create some different binary MMS message files for you to try to see what we can figure out.

Bryce,

Thanks for the help, I have been too busy with other things and are now just getting back to this.

I do not have any definitions set in my MMSC routing tab, yet I am still able to send MMS messages to other Cingular subscribers. Do I need to configure something in this tab?

I also tried making the change you suggested and that did not make a difference. I am still able to send MMS to cingular users but not to Verizon users.

Looking at the MMSlog, I do see a cingular IP picking up the message, I presume the phone itself maybe? But do not see it picked up when I send the message to a vzw phone #.

My testing is made rather difficult because of the delays in the mms relay between cingular and vzw.. sometimes it takes more than one hour for the messages sent (manually) from the cingular handset to make it to the vzw handset.

Thanks again for all your help, and look forward to more troubleshooting.

More information.

I added an MMSC route, filled it out completely, and hit the "test" button and everything passed.

Made this route the default route

Made sure that I followed the instructions above.

I can still send messages to Cingular users, albeit they take MUCH longer to go through the network it seems. After NowSMS logs a MMSOUT mesage it may take 10 minutes or so for the message to make to the intended phone.

However messages are still not getting to vzw users with or without the MMSCOMPParameters parameter set.
