i did a small test and yes indeed, as mentioned above..its not a problem with any jailbreak or unlock to the iphone....what i did was swap my tmobile sim and inserted an att sim and called my iphone to see the results......when the call connects to voicemail, it simply shows up on the screen as a missed call...but once i inserted back my tmobile sim and called myself....it showed call failed on the screen....my conclusion , its a problem with tmobile...since the iphone was designed to work with visual voicemail on the att network....it has somekind of interference once it connects with the tmobile voicemail causing it to display call failed..
