How do I increase the number of rings before calls go to voicemail?

Hello campwk and welcome,

The easiest means by which to change the number of rings before a caller goes to voicemail is the log into the Business Class Portal (BCP) Administrators Email account, then click on the Phone link or Icon which takes you to the Digital Voice Center (DVC). You must login to the DVC using your 10 digit telephone number (just the ten consecutive digits) then use one of the following: Voice Mail passcode or Customer Proprietary Network Information (CPNI) 4 digit security pin US Mail to your service or billing address 7-10 days after your services were installed. 

Once you are able to enter into call control features, click on messaging, then click on greeting link and vertical scroll down until you see # of rings, then click on the down arrow button and select the number of rings you want , then click appy and/or save.

Hope this helps you out.
