As T-Mobile charge me for voicemail collection and charge all call diverts as out of plan calls (so I can't divert voicemail to my home phone and collect later) I was wondering if it was theoretically possible to have a local answerphone/ voicemail box set up on the n900?

If it's more than theoretically possible and an app exists please can someone point me at it?

Stupidly I didn't check the VM charging situation before I changed from Orange to TMobile - on my particular Orange plan it was inclusive, so I assumed that was standard! Ha! How niave am I? lol
