Hi

Thought we'd try out the Multimedia WAP Push functionality using a Nokia 3650 (Vodafone), however we get the error:

"Bad answer from origin server"

displayed on the phone when trying to open the link.

Any idea why? Normal WAP Push works OK.

Cheers

Matt,

What port is your MMSC configured for ("HTTP Port" on the "MMSC" page of the configuration dialog)?

When you do the multimedia WAP push, the MMSC is used as the content server ... and in my experience the Vodafone WAP gateway doesn't like content servers on ports other than 80.

I just tried it on a 3650 here, and it worked just fine (although I don't have a Vodafone SIM handy, so I can't test through the Vodafone gateway).

Hi Bryce,

It's actually set up on 8880 because it's co-located on a Web server (which obviously uses port 80). I'll have to try it on a different port somehow...

Cheers

Matt,

I'm pretty sure access to content servers on ports other than 80 is still a problem on Vodafone. Some operators have firewall settings that serve little purpose.

To confirm this, put a simple WML file in the MMSCDATA subdirectory of NowSMS. For the sake of this example, let's call it test.wml.

Then request http://server.address:8880/test.wml.

Assuming the response never makes it to the phone, check the MMSC-yyyymmdd.LOG file to see if you see any requests coming in.

I'm suspecting that when you use the Vodafone WAP gateway, the request won't go through.

On your co-lo server, can you get more than one IP address allocated to the server? If so, then you can have IIS listen to port 80 on one address, and NowSMS on another. See this link for more info: http://www.nowsms.com/tb/TB-NOWSMS-004.htm

I am having the same problem while testing with a Sony Ericsson T610 (MobileOne, Singapore).
I tried sending a small (2k) GIF to the phone and it sucessfully received the WAP Push message. The phone displayed the Sender and Subject but when I tries to load the URL, the phone returned an error stating "Item not supported, cannot be downloaded". In the MMSC log however, the phone requests for the WML did come in.
I also tried access the same URL using Blazer on the Palm OS Emulator and this time, 2 entries were added into the MMSC log, first for the WML file and another for the image file.

Beng-Keong,

Hmm ...

I am wondering if there is an issue with the M1 WAP gateway? Maybe it does not like the MIME content type for GIF?

Have you tried sending a WBMP file (just wondering if that makes a difference)?

For troubleshooting purposes, I wonder if it is possible for you to try connecting via our WAP gateway at IP address 213.48.20.10 (you would need to use a GPRS APN that allows you to access external WAP gateways, and I am not sure what that would be for M1 ... it is usually whatever APN is used for regular internet connections).

Hi

I tested with your WAP gateway and it worked once (on 02/07 afternoon SGT) but I had not been able to get it working again today (03/07). Error message from the phone indicated a communication problem. Back when it was working, I was able to view the message with a strunk down image (JPG) and I was able to download the actual image into the phone.
Next I tested again with our inhouse WAP gateway, running Kannel 1.2.1 and it succeeded in downloading the page with the smaller version of the image. However I was not able to download the actual image. The error was still the same "Item not supported...".

Hi Bryce

More testing done on the SE T610. This time, I tried using the Ericsson WAP gateway at 193.95.167.178 and this time, the WAP gateway returns an error page. The content was:
The page was malformed.
With a link to a technical description page which reads:
XML error = 'alt' attribute unspecified (before or at line 13)

It looks like some WML error in the message page. Is there a template file anywhere in the NowSMS installation which I can customise to change this? Or I have to wait for the next software update?

Enough testing for now.

Beng-Keong,

Sorry for the delay getting back to you. I actually know about this problem. Some phone/gateway combinations do not like the fact that we did not include an "alt" tag on our "img" link.

You can download an update at the following link which does address this problem:

http://www.nowsms.com/download/nowsms420a.exe

This is a later build of the v4.20 release that corrects a few minor problems, including this one.
