6600 - voicetags

Just upgraded from my trusty 6310i. On that phone I had multiple voicetags
for a contact eg I'd have "mobile", "office", "home" set-up. When I try to
do this on the 6600 it says I already have a voicetag for that contact do I
want to delete it, I say no thinking this is the way it lets you add another
tag, but it just cancels out. I could set up separate contact entries for
the separate voicetags but it seems a backwards step.

In addition if I try and change a voice tag by re-recording over an existing
one I press start and then get Voice System Error.

Phone is on Orange and has latest firmware (V 3.49.1 05-12-03 NHL-10).

Anyone experience this?
