Sorry for the spam in the forum ^^
i wanted to know the behaviour of the uaproof flow.
in order to restrict the http flow on the destination on our Firewall , i did try to understand the uaproof.
As far as i saw , when the mmsc doesn't have the type of the mobile in the uaproof directory , it does a request , and put the xml ( or rdf , .. ) in the uaproof directory and update the uaproof.ini. The x wap profile indicate what url has to be requested by the mmsc on the notify resp-ind.

My questions are the folowing :
- if the mmsc has no internet connection , does the mmsc will send the mms on a default settings , or reject it ?
- is it possible to use a proxy directly on the mmsc tools for the uaproof request or directly configure a proxy on the network configuration from the windows server that host the mms service ?

Thanks beforehand for your feedback,

Hi Marc,

You can use a proxy. Edit MMSC.INI, and under [MMSC] header, add UAProfProxy=ip.address:port to specify the IP address and port of the HTTP proxy.

Generally speaking, since all modern devices have similar capabilities, the UAProf is not as important as it was in the early days of MMS. If the MMSC cannot load one, it assumes the receiver has no limitations, which is generally a good assumption these days.

Unfortunately, there is no setting to disable the lookup. This issue generally not a problem, as long as the attempt to fetch the UAprof fails quickly. If the network config is such that it takes a long time to resolve and fail the lookup, this may cause the receiver to timeout when downloading the MMS. We should add a setting to allow the lookup to be disabled...but as a work-around, you could point the UAProfProxy to an invalid local address like, so that it fails quickly.
