Union Telephone v2009.06.11

I attached the .MMS file of the message with the problem. When I sent the message to a phone, the picture and text would not display, but it gives me away to select the attached picture or text to view.

I looked in the .MMS file and it does not look like the picture and text ids in the smil match the names of the attached picture and text.

Thanks,
Joseph

This message was received via MM4.

Hi Joseph,

Is there any chance that you can capture a raw message coming in via MM4 in addition to this?

Unfortunately, I'm not sure of a good way to do that quickly...and I need to head out for a few hours.

The issue is that it depends on whether or not the "Content-ID:" fields were present in the original message when it came in via MM4.

From the looks of things, it looks like the Content-ID fields were missing from the message when it came in via MM4 ... so they didn't get converted over to MM1.

It's always possible that the fields were present, but that there is something unusual about them that is causing them to not be interpreted correctly. But unfortunately, it's more likely that they are already missing when they are received via MM4. That is what we need to see.

We may need to change the MMSCDEBUG.LOG handling to make sure the full MM4 content gets logged, as that would make this a lot easier to troubleshoot ...

Hi Des,

The problem is repeatable. Therefore, I would be able to do the capture.

Thanks,

Joseph,

I ran some tests, just to make sure that we didn't miss something in the recent updates.

But the "content-id" translations to/from MM4 seem to be working properly.

I suspect the SMIL is coming in with the "cid:" references which point to objects in the MMS message by their "Content-ID:" header instead of their name. But that the MM4 content that we are receiving is missing the actual "Content-ID:" headers.

It would be a lot easier if we could just enable the MMSCDEBUG.LOG to look at the raw MM4 message that is being received. Then we could see if the "Content-ID:" headers are or are not there.

If they're missing when we receive them ... then I'm not sure what we could do.

But maybe they are present, and there is something unusual about the headers that is giving us problems. I don't like it if the problem is ours, but if it is in our control, at least we have the ability to fix it.

Unfortunately, I'm suspecting the latter.

Since you're running such a fresh version, I'd suggest updating to 2009.06.30 which is now available at http://www.nowsms.com/download/nowsms2009rc.zip.

Enable the MMSCDEBUG.LOG, and we are now logging the complete detail of the raw message received over MM4.
