Hello,
the NOW MMS gateway works great. I have no problems sending MMS over the internal MMSC or sending WAP Multimedia Push Messages from the WEB Interface.
Then i started using the "Convert MMS to WAP Multimedia Push"-Option. The generated WML-pages are rejected by most WAP-Gateways i tried and if they get through some phones doesn't like them. The picture is not very coherent. I think the problem is the Reply-Option in the generated wml-page. If i try to download the page without the "?id=phonenumber" added to URL, it works. I downloaded the page with my PC-Browser (with id) and the wml-page looked quite normal. The phonenumber was correctly inserted. Then i put this file in the MMSCDATA-Folder and the phone displayed it! But when i added the "?id=xxx"-part i run again into problems. It depends on the length of the phone number. For up to 12 Characters (including numbers,letters or the %2b for the "+") it works, but if the string gets longer the generated page may look perfect but won't get through the gateway. I hope this description is correct, since i discovered this behaviour some days ago. I know this sounds very weird and i just don't understand it.
But apparently i am not the only one having problems with wap-push, regarding these threads (http://support.nowsms.com/discus/messages/485/7096.html and http://support.nowsms.com/discus/messages/485/7113.html ) in the last days.

It would be good to have the possibility to turn off the reply-part in the WAP Multimedia Message.


I tried to use the new WAP template feature. Well, the reply-part is absent know, but the "Download as an MMS"-part is placed before the header...

<br/><a href="/20041106/05/xxxxxx-notify.mms">Download as an MMS Message</a><br/>(not available on all phones)<br/>
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<card title="something">
.....

How can i turn off that part? How many phones really understand the "xyz-notify.mms" file? It worked with a Nokia 6230 that connected directly without a proxy to the MMSC, but it failed for instance with a 3650 or Sharp GX10.
With best regards,
Oliver

Oliver,

I'm sorry, but I am really confused.

And looking at the other problem threads that you have referenced, I don't know what they have to do with your problem. Neither seems to be dealing specifically with the Multimedia WAP Push functionality.

So let's deal with your issue.

I'm really confused that you are seeing this "Download as an MMS Message" prompt ... and the reply option.

Those features were experimental, so it puzzles me that you are seeing them. They should be disabled.

But I do see what you mean. It looks like some recent change caused them to be enabled if you set the default "MMSC Routing" to be "Convert MMS to Multimedia WAP Push".

My suggestion is to define an additional route where the route is set to "Convert to Multimedia WAP Push". Then set that as the default MMS outbound route.

That should remove the "download as an MMS" and "reply" text from the template. Meanwhile, we need to make sure that these experimental features are removed completely.

Moving past this, do you still see problems with the URL?

Thank you Bryce,
that was the solution. It works when i define an additional route. The URL-problem has also disappeared since then.

However, i discovered a new problem with the WAP template function. If i am using a template file, non US-ASCII characters are not correctly displayed. The UTF-8 conversion/support seems to be not working properly under these conditions.


Examples from the generated WML-files:

(without template file:
ae - &#228; &#196;
oe - &#246;
&#214;
ue - &#252; &#220;
sz - &#223;
EUR - &#8364;
Ct - &#162;
o2 - O&#8322; )

(with template file:
ae - &#195;&#164; &#195;&#132;
oe - &#195;&#182;
&#195;&#150;
ue - &#195;&#188; &#195;&#156;
sz - &#195;&#159;
EUR - &#226;&#130;&#172;
Ct - &#194;&#162;
o2 - O&#226;&#130;&#130; )

It is not a big problem, i can cope well with the standard version without a wml-template.

Hi Oliver,

I'd have to see the examples of the template and the generated files with and without the template in order to understand.

But keep in mind that we assume that the encoding in the template is UTF-8, so you should start off the template with the following header:

<?xml version="1.0" encoding="utf-8"?>
