:(
please somebody help...
i used a <mobile:call> control in one of my mobileform, and when it is rendered in:

1. nokia 5100 SDK: when i click the call control, it said "File format unknown". when i looked at the result of wml rendering in the SDK browser source, it is written "<a href="wtai://wp/mc;0217669000?mobileAcc=$(mcsv0)" title="Telepon">Call Center</a>".

2. openwave 622 SDK: it can't even process till the page containing the mobile:call, because when there is a button click. it said "malformed server response" whereas i've already add the new file types needed in the mime map.

3.openwave 4 SDK: same with the openwave 622 sdk case. but with the different error message : "translation failed for content-type: text/vnd.wap.wml

4.nokia s40 sdk1.0(resemble N6230 interface): everything went normal, except the result of the mobile:call control cannot be clicked. it is rendered like in the IE. only in text format.

when it is rendered in IE, everything run properly.

notes: i used the cookieless authentication, so the URL became too long. and the mobile:call control is included in the authenticated page. is it something to do with the problem? because when i tried to use the mobile:call control in a newly created page ( didn't use authentication) everything run normal: "<a href="wtai://wp/mc;0217669000" title="Telepon">Call Center</a>".

it is really a complex case. i'm desperate.:(
