Professional Answering Machine Greetings Does Anyone Know Of A Software I Can Install For Voicemail Answering?

Does anyone know of a software I can install for voicemail answering? - professional answering machine greetings

We have a small office at home and need help.
In the past, we have access to online software that would handle calls for voice mail when we have had. Since then the track and have a professional image.
Can anyone tell me where I access the voicemail software? ... Freeware, if we can get.
Thank you.
PS. We currently have an old answering machine that works well any more.
