My phone is K X _TG 5240 how can i increase the # of rings

SOURCE: LINE 3 RINGS ON ONE PHONE- AND DOES NOT RING ON THE OTHER 3...

You will have to get into the programming mode and change Memory Block 4-01 for the port of each phone you want to ring. The corresponding light for the button is OFF for no ring, GREEN for ringing, and RED for delayed ringing.

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.
