The 724 number will be a fax number. It would be tied with the VOIP service, and will use a DECT ATA to manage incoming and outgoing faxes. I don’t need to fax often, but I would rather have it and not need it, then need it and not have it. I will need to acquire a printer that would support fax capability, but this will be easy enough if I had a windfall of money. Still, I would expect that I might have more of reasons to needing a fax service even if I don’t right now.
