It has now been 4 months since we dumped the old dedicated fax #, and no one has noticed or cared.
The shop is currently using an ATA (analog telephone adapter) with voice over ip, going to a cordless phone base that has 4 handsets all over the shop. We ordered our first (Polycom) business IP phone last week, and it should be here next week. This device will plug directly into Ethernet to talk with the provider, and promises HD VOICE (voice clarity up to 4x greater than anything else so far, assuming the person on the other end has it too. most cell phones support this technology now, too) One advantage to the ip phones is that they're portable. I could get one for home (or take this one home), for example, and it would work the same as long as it was plugged into ethernet. For now, it's going to sit next to the main POS station at our design counter. For a provider, we are using Verizon BDV (Verizon Fios/Fiber Business Digital Voice). They are technically buying the voip service from cloud provider Broadsoft. We did have some serious problems at first with dropped calls, and eventually figured out that it was due to bad firmware in Verizon's newest router. It has a reliability issue dropping the signal every 3 minutes briefly, sensitive enough to knock out the ATA but not the computers using the internet. They downgraded us to the previous model, for now, until it gets fixed.
