What Is A VoIP Phone?
VoIP phones use VoIP technology to transmit voice calls and messages over an IP network. Whether hardware or software-based (softphones on laptops/desktops), they enable connections similar to WhatsApp or Skype calls.
Now, let us look at the differences between a VoIP, Traditional and an IP telephony.
VoIP vs Traditional Phone Systems vs IP Telephony
VoIP and IP telephony are often used interchangeably. IP telephony refers to digital phone systems using the internet, unlike traditional analog systems. Whereas, VoIP is a type of IP telephony that prioritizes and transmits voice traffic over the network. Essentially, they mean the same thing.
On the other hand, Traditional phone systems transmit calls through landlines, limiting users to their desks without internet access. This lack of flexibility has led to the decline of landlines in homes and businesses. And it is important to consider that organizations these days seek more agile systems to support growth.
The table below provides a concise overview of the main differences between VoIP Phone, Traditional Phone, and IP Telephony systems.
| Characteristics | VoIP Phone | Traditional Phone | IP Telephony |
|---|---|---|---|
| Communication | Voice over Internet Protocol (VoIP) | Analog transmission over landlines | Digital transmission over the internet |
| Network | Utilizes internet connection | Relies on landline infrastructure | Utilizes internet connection |
| Flexibility | Allows mobility and remote access | Limited to physical location | Allows mobility and remote access |
| Features | Offers advanced features like call forwarding, voicemail to email, etc. | Basic call functions | Offers advanced features similar to VoIP Phone |
| Cost | Generally cost-effective, especially for long-distance and international calls | Cost varies based on provider and usage | Generally cost-effective, similar to VoIP Phone |
| Installation | Requires internet connection and VoIP service setup | Plug into existing landline infrastructure | Requires internet connection and setup of IP telephony system |
What are the types of VoIP phones?
There are two main types of VoIP phones:
Hard Phones:
These are physical telephones that transmit voice signals through your internet connection. They plug directly into your business network for operation.
Pros of Hard Phones:
- Familiarity: They resemble traditional phones, making them easy to use for employees familiar with landline phones.
- Durability: They are typically built with sturdy materials, making them more durable than software-based alternatives.
- Advanced Functionality: Often equipped with advanced features tailored for VoIP technology, it enhances communication capabilities.
Softphones:
Softphones are software-based versions of telephones that can be installed on various devices with an internet connection. They provide mobility for users to make and receive calls from anywhere and are ideal for remote workers or those frequently on the move.
Pros of Softphones:
- Mobility: Softphones can be installed on various devices, enabling users to make and receive calls from anywhere with an internet connection.
- Flexibility: Softphones are ideal for remote workers or employees frequently on the move, offering flexibility in communication methods.
- Cost-Effectiveness: Generally cheaper to implement and maintain than hard phones, as they utilize existing hardware and require less physical infrastructure.
VoIP Phones: How Does Work?
VoIP phones, whether hard phones or softphones, operate similarly by leveraging internet connections to transmit voice signals instead of traditional phone lines. Here’s a simplified explanation of how VoIP phones work:
Let’s walk through a real-life scenario involving a user named John using a VoIP phone with a service provider like MirrorFly:
Stage 1: Preparation
John, a business professional, needs to make an important international call to a client. He picks up his VoIP phone, which is connected to his office network.
Stage 2: Call Initiation
John dials the number using the keypad on his VoIP phone. The phone’s interface displays the number as he enters it. He then presses the call button.
Stage 3: Analog-to-Digital Conversion
As John speaks into the phone’s receiver, the analog sound waves of his voice are converted into digital data by the phone’s built-in analog-to-digital converter (ADC).
Stage 4: Compression and Packetization
The digital voice data is compressed and divided into small packets by the VoIP phone. Each packet contains a portion of the voice data along with routing information.
Stage 5: Transmission
The packets are transmitted over the internet through John’s office network. The VoIP phone is connected to the network either through an Ethernet cable or Wi-Fi.
Stage 6: Routing
The packets travel through various network devices within John’s office network, such as routers and switches, before reaching the MirrorFly servers.
Stage 7: MirrorFly’s Infrastructure
MirrorFly’s servers receive the packets from John’s VoIP phone. They process the packets, handle call setup procedures, and route them towards the recipient’s device.
Stage 8: Interconnection
MirrorFly’s servers may interconnect with other networks or service providers to facilitate communication with the recipient, who may be using a VoIP phone or a traditional phone connected to the PSTN.
Do you know?
You can also host your app on your own company servers, while leveraging MirrorFly’s custom solution?
Stage 9: Destination
The packets reach the recipient’s device, whether it’s another VoIP phone, a VoIP application on a smartphone, or a traditional phone connected to the PSTN.
Stage 10: Decompression and Playback
The recipient’s device receives the packets, decompresses the digital voice data, and converts it back into analog audio signals. The recipient hears John’s voice through the device’s speaker or headset.
Stage 11: Conversation
John and the recipient engage in a conversation, discussing business matters and exchanging information.
Stage 12: Call Termination
Once the call is complete, either party can end the call. The VoIP phone terminates the call connection, and any remaining data packets are no longer transmitted.
Throughout this process, John’s VoIP phone, the network infrastructure, and MirrorFly’s services work together seamlessly to enable efficient and reliable communication over the internet.
What advantages do VoIP phones offer?
Businesses are increasingly switching to VoIP phone systems due to several advantages:
- Flexibility: VoIP allows for flexibility in call routing and handling, enabling businesses to customize call flows based on their specific needs and workflows.
- Remote Collaboration: VoIP facilitates seamless collaboration among remote teams through features like video conferencing, screen sharing, and instant messaging.
- Global Reach: VoIP enables businesses to establish a global presence by providing local phone numbers in different regions without the need for physical offices or infrastructure.
- Budget-friendly: Compared to traditional phone systems, VoIP offers cost-effective solutions with manageable monthly fees, avoiding large hardware investments.
- Disaster Recovery: VoIP systems offer built-in redundancy and disaster recovery capabilities, ensuring business continuity in the event of network outages or natural disasters.
