I record and send a voicemail every morning to two co-workers(both Verizon phones) often but not every day one co-worker will not get the voicemail...also I have assigned each number a "group distribution number"....I have do do it that way because when I enter the 10 digit phone number 9 times out of 10 it tells me that the number I entered is not a valid Verizon number(even if it is) . Can I get some help on this?I've tried calling and talking to a Verizon service rep but cannot resolve issue?? Also anyone know of a good replacement app that works with Verizon?? Thanks
