Thanks for your effort, but this doesn't seem to be the problem, otherwise the
optimize-notification-size would have worked. I will investigate further.

Subject: Re: MMS notification problem
What we do in Mbuni conforms to the MMS spec published by the Open Mobile
Alliance, so we didn't just make the decision ourselves. Like I said, forget
PPG. MMS spec does not use that stuff. My guess is the other phones do not like
the IP address as a sender. You need to tell Mbuni how to resolve IP addresses
to MSISDNs at the time of MM1 sending (docs, mailing list...).

Hi,
Interesting. I just printed the notification mbuni sends. It is just a
collection of X-mms headers. No body whatsoever. Further investigation shows
that notification is dropped only by certain phones. I did my tests on a Nokia
73 mobile. Logs from kannel's PPG are ppg 1.2.1 SI. I still haven't met a phone
that doesn't support it.
Any reason you have gone with the MIME format instead of the PPG? Is the
spec, as usually, vague on that? Do you think that it would be useful to
replace that part of the code for si encoding from kannel's lib?
P.S. I am relaying the MMS from another mbuni over MM4 (Remember my last
week's MTA questions?). That's where you are getting that IP address.
Thanks,
Nikos

What I meant was that the from address in the MMS
(94.143.177.172/TYPE=IPv4) is an IP address. What kind of message are you
sending using Kannel's PPG? Note that the MMS notification is not wbxml
formatted. Rather, the MMS spec uses a format adapted from the WAP compressed
MIME format from the WAP-203-WSP spec. Therefore you can't compare the two
cases exactly.

Hi,
I fully agree that it shouldn't be happenning. But I have no other
option than to verify with the debugger. Everything else matches: udh, from,
to. So the only offending part *must* be the wbxml-encoded text. By the way the
from: field in the notification is "AMD" not an IP address.
I also checked the optimize flag you mentioned. Same behaviour, mobile
receives it, but doesn't display it.

Like I said: This part has worked since the beginning, so the problem
is not in Mbuni. Some phones are a little picky about notifications: I see
that the sender in your case is an IP address. This can cause problems. Also
try the Mbuni optimize-notification flag (set to true) and see if your mileage
improves

Notification never shows in my mobile. I ran a test with wapbox and
the ppg came fine in the same phone (same DLRs). So it is not a phone problem.

UDH is the same in both cases. Text, of course, is different. >From
my experience a lot of mobiles won't display ppg if they receive corrupted
wbxml. There is a difference in the dlr-mask, but it is not important. mbuni's
notification is not received whether dlr-mask is set to 0 or 63.
BTW: Why the _dummy=x variable that mbuni inserts in the URL?
Thanx,
Nikos

This part of Mbuni has worked for the last six years, so it is
unlikely that there is a bug. What is the URL from the logs?

I dunno. It seems to be an mmsrelay problem. I am in the middle
of something similar now, seems that mbuni (mmsrelay) might be generating bad
wbxml. In my phone I never see the notification, despite receiving it (verified
by DLR). Tomorrow i will look more into it.
