I have an 8820 and use it via bluetooth in my Merc. When I receive a call it is not the ringtone I have in my profile. How can I set this?
Also, if I am on a call and receive another call at the same time it rings for ages before diverting to my voicemail. How do I change the amount of rings before divertinbg? I am using Orange system in UK.

I have moved your question to a new thread. Please don't post new questions within existing threads.

For the ringtones make sure everything is set correctly: How do I edit my notification tones (profiles)? - BlackBerryFAQ

And check this FAQ for the voicemail ring issue to see if it works for your carrier: Increase amount of rings before voicemail - BlackBerryFAQ
