the voicemail ring count has to be setup on your phone line thru your voicemail menu,and has nothing to do with the answering machine. if you don't want the answering machine to pickup, just shut it off. follow the prompt's for your voicemail settings, there you'll be able to set the amount of rings you want.
hope this helps.

By default individual coverage is set to 45 seconds. Ask your phone vendor to reduce it.

The change is made in the voicemail system, not the phone. Get in to your voicemail box, listen to the menu and select the option for 'setup', 'settings' or 'system options', the exact name varies according the voicemail system, and you usually have to make several choices, but the options are almost always availble with menu selections. With hundreds of voicemail systems available, that's about the best advice you'll get with the information you provided.

Is your system a BCM or a CIC/MICs system?

I know you most likely will not know, so I will give you both ways to change this... they are pretty well Identical, but there is one extra set if your system is a BCM, that is if the set programming can be done.

ok... lets get started!
Go to a programming set:

-> FEATURE * * 2 6 6 3 4 4 (CONFIG)
-> User ID: 7 3 8 6 6 2 (SETNNA) [this is the extra step I was talking about]
-> Password: 2 6 6 3 4 4 (CONFIG) [this is the default password, but could have been changed by the programmer]

Now you will have to look at your LCD for 3 arrows
<- Heading....Enter->
<- Back .......Next->
You will not see these words in the LCD display, you just have to look for the 3 arrows that correspond.

-> You will now see TERMINALS&SETS, and press the ENTER button
-> type in the extension of the set (eg:2338), now you will see 2338: NAME
-> press ENTER and you will see LINE ACCESS press NEXT till you see CAPABILITIES
-> press ENTER and look for Call Forward No Answer
-> press CHANGE and type in the new name pressing the # button to advance to the next letter.
-> Hit the NEXT button to save
-> press the HEADING arrow to back up and press FIND to look for next extension that you want to change.

-> after all the changes are made, press the RLS button to end programming.

The Voice Mail feature is set by your phone company, not by the phone. Typically the phone company will set it for 20 seconds, or approximately 4 rings. This is called your voice mail "Ring Cycle"

Call them up (the customer service number should be on your phone bill) and they should be able to increase or decrease your ring cycle for you at no charge.
