FAQs/International Calling & Rates

General Information

Voice over IP refers to a method of transmitting phone calls using the Internet or other data network, instead of using traditional phone lines. The main benefits of this technology are reduced costs and features that integrate voice and operational data.
Instead of having a phone system inside each office, a hosted solution is located centrally, typically in a hardened data-center, and connects to phones at each location using the Internet. The main advantages of such a solution are reduced costs since there is no need for a phone system at each premises, and increased reliability, since the central location has backup power, network access and other facilities to ensure maximum availability.
To use 4Voice business service you will need broadband internet access such as Business Cable, DSL, T1 Lines, Metro-Ethernet, FIOS etc. You will also need one or more Voice Over IP phones, or soft-phone applications that can run on your PC.

Yes, 4Voice Business Phone Service will let you dial 911 from your office and provide the correct address information to the 911 agency. Note that the following important restrictions apply to this service:

The address shown will be the latest address that we have on file for your business. If you relocate the office or a phone in the office without notifying 4Voice, then the address will not be updated.

911 will not work if your internet access is down or you have no power.

4Voice Business service offers two options for fax:

Inbound and outbound e-fax services let you send and receive all your faxes via email. Alternately, a Fax Adapter lets you use your existing fax machine with 4Voice Business Services.

If your internet access fails, calls will be automatically rerouted to an alternate location or to backup phone numbers that you define beforehand. Your calls will always be answered and then directed to an appropriate destination, or to voicemail.

For further reliability, you can use two independent internet access providers (DSL and Cable for example) to prevent against a single failure—4Voice Business services will run over both of them seamlessly.

Prior to activating your service, our experts will evaluate your internet access to ensure adequate bandwidth for your business needs. Our solutions use ‘traffic shaping’ routers that prioritize voice calls over data, so that there is no disruption of phone calls due to internet traffic.

The only requirement is that remote workers must have broadband Internet access along with a router. They will need to be provided with a VoIP phone or a soft-phone that runs on a PC (note that the VoIP phone cannot work over Wi-Fi, and needs a wired network connection).

Depending on the size of your business, you may need internet service ranging from Basic DSL to high speed access such as a T1 line or metro Ethernet.

There are two options for backup power for the phones:

Each phone can be plugged into a small UPS backup battery, which will keep the phone running in the event of a power outage. This can typically also be used as a backup for your PC.

Alternatively, a larger central backup battery can be used in combination with a “Power-Over-Ethernet” (PoE) Ethernet switch. In this configuration, the phones draw power from their network connection, which is then backed-up centrally

Note that in addition, any broadband internet access equipment must also have backup power in order to continue phone service after a power outage.
