Number of rings prior to voicemail kicks in

I am having trouble with answering my phone before voicemail kicks in. It only rings three times then goes to voicemail, which is more often than not too short and I then have to call the person back. It's a real pain. Any suggestions?

Pamlamb I'm looking into this question on behalf of another member so once I have some information I'll update you on this topic.

Yes me too. A real pain in the Ass.
