How VoIP Phone Service Works

Voice over Internet Protocol (VoIP) converts your voice into a digital signal, compressing it, and sending it over the internet. VoIP can be used from a computer, VoIP phone, or traditional phone connected to a special adapter. You can also use VoIP wirelessly at places with internet access, like airports, parks, and cafes. It offers a cost-effective business phone solution because it bypasses phone lines, instead using your existing internet infrastructure. 

VoIP (noun): Voice over Internet Protocol (VoIP) is a technology that allows users to make and receive phone calls over the internet instead of using a traditional phone line.

VoIP offers several advantages to traditional phone lines.

  1. Video: VoIP can support video calls in addition to audio. 
  2. Call recording: VoIP can record calls for quality or regulatory purposes. 
  3. Flexibility: VoIP numbers are not associated with specific devices. Rather, they can be associated with a main company number, a group, a call flow, a person, or even a greeting alone. Users can log into their account from any device with an internet connection.
  4. Cost: VoIP is often less expensive than traditional phone service.

What is a PBX?

PBX (noun): A Private Branch Exchange (PBX) system, services a private network of telephones in an office and acts as a gateway from a company to the outside world.

Internal Communication: PBX systems connect extension phones within an office to each other. 

External Communication: PBX systems allow users to share a limited number of external phone lines. 

Features: PBX systems offer features like call queueing, conference calling, and enhanced security. 

Cost: PBX systems save money by eliminating the need for each user to have their own line to the telecommunication company. 

Ownership: The business owns and operates a PBX system, not the telecommunication company.

Maintenance: Traditionally, IT professionals have maintained PBX systems, but today systems are much more advanced. All VirtualPBX Business Phone customers manage their systems with no technical expertise required.

Networking & Connectivity

VirtualPBX Business Phone plans are dependent on an internet connection. Internet connectivity has improved greatly in many areas as traditional telephone wires become more difficult and expensive to maintain, however it is important to understand the nuances of your connectivity.

Is my internet fast enough for VoIP?
Speed alone does not guarantee optimal VoIP results—it only takes about 100kB up and down for a phone call. It does, however, need a consistent and reliable connection for quality VoIP calls. If you are experiencing issues with your phones, it could be related to your network specifications and settings. Use our free VoIP speed test to determine your current capabilities.

One setting in particular is SIP ALG, which should be disabled if you are experiencing issues. If you have any questions regarding a malfunctioning VoIP device, please contact our support team.

Can my VoIP device function over a wireless internet connection?
While older desk phones do not support connection over WiFi, newer generations have a built-in wifi capability or a WiFi dongle that allows connection through WiFi. Additionally, apps like the softphone and web phone can use both WiFi and data connectivity. Check the specifications of your device to determine specific WiFi support.

What happens if my network goes down? Does it affect my VoIP device?
While VoIP relies on an internet connection, because your phone system is in the cloud, it continues to function. If  your internet connection is down, it’s possible that your VoIP devices are down as well, but it depends on how they are connected. If a hardware device is plugged into WiFi and WiFi is out, the phone is also out. However, devices like apps also run on data and your LTE connection is often stable. Call forwarding is also an option, which skips your internet connection entirely and routes over PSTN. Data rates depend on your provider, but call forwarding could be your default route to help manage how data is used. Network redundancy paired with a strong backup plan can proactively reduce the impact and keep your devices online.

Connecting your desk phone to the network.
In addition to the web phone and softphone app, you may want to connect your desk phone(s) to the network. This process is fairly simple and our Customer Experience team is standing by to assist as needed.

  1. Plug in the power cord to a power source.
  2. Plug one end of an ethernet cable to the LAN port of the phone, and the other end into a network device with a valid internet connection (Gateway, switch, router, etc)

    You may plug in a SEPARATE ethernet cable, with one end in your PC/Laptop and the other end in the PC port of the device, if you wish for your phone to be a passthrough for your internet connection.

  3. Phones purchased from VirtualPBX come pre-provisioned. Once connected to the internet, the phone will automatically program as indicated at onset.

Depending on your device type and the make and model of your device, there’s a specific button on your phone to put calls on hold. Press the “hold” button to put the call on hold.

Checking Voicemail On Your Phone
Press the message or voicemail button on your phone to quickly and easily retrieve your voicemail. Once pressed, enter your voicemail number then the # key, followed by your PIN and the # key again.
