How does VoIP work?
VoIP works by converting the analog voice signal into digital data packets that are in turn transmitted over the Internet traveling between your phone and a VoIP provider. The voice signal is divided into packets and sent over the network until it reaches the recipient. Once there, the packets are reassembled and converted back into a voice signal so the recipient can hear the conversation. Because no physical installation is required, this type of technology offers many benefits and makes it an excellent option for businesses and individuals who want to save on telephony costs.
VoIP Calls: How to call via VoIP?
VoIP calls or internet calls are phone calls made over the internet. To activate this service you need to create a VoIP account using a SIP trunk to be able to call from a computer or smartphone. Users who use VoIP technology can make their calls through IP devices, Softphones, and/or by connecting conventional analog phones to a VoIP network through an analog telephone adapter (ATA).
You can check the VoIP call rates to see how much domestic and international calls cost.
Below we give a brief definition of the devices you can use to make VoIP calls:
- VoIP devices: They look much like traditional phones, but have an Ethernet connection instead of a phone connector. They are normally used as extensions in PBX or Virtual PBX systems.
- Softphones: These are VoIP software applications that run on a computer or mobile device and allow making phone calls over the Internet. These softphones can be very useful for those who want to use their computer or mobile device as their main phone device. They can also be used as extensions of a cloud PBX.
Advantages of VoIP for Businesses
VoIP has several advantages compared to traditional telephony that can be leveraged by businesses. Some of the main advantages are:
- Free extension-to-extension calls no matter where you are: This benefit helps reduce costs considerably if we consider that remote work is becoming more popular in the business world every day. For example, when implementing a cloud phone system you can call other members of the company for free without the need for expensive equipment or phone plans, regardless of the country where you are.
- Lower cost international calls: VoIP calls are cheaper because they use the internet to transmit voice instead of traditional fixed and mobile telephony networks. By not requiring expensive infrastructure, such as landline or satellite telephone lines, companies can get calls at lower prices.
- Advanced features without physical hardware: Because VoiceToPhone offers cloud telephony services, there is no need to invest in expensive infrastructure. Additionally, VoIP telephony offers many advanced features, such as call recording, queues, voicemail, call forwarding, among others.
- Portability and flexibility: You can access your cloud phone number from any device connected to the Internet, allowing you to work from anywhere.
- High Audio Quality: Although audio quality depends on the quality of your Internet connection, the sound offered in VoIP is excellent.
- Integration: VoIP can integrate with other business tools such as email or instant messaging, which are part of unified communications. It can also integrate with other third-party software or custom development to allow users to make phone calls within them.

Differences between IP Telephony and traditional telephony
The most important difference between these two technologies is the savings. VoIP telephony has the advantage of being stored in the cloud and therefore it is not necessary to use wired connections, nor to make installations or maintenance of physical equipment to put it into operation, which in turn brings benefits such as mobility and productivity that are necessary in today's business world.
IP Telephony
Traditional Telephony
No need for wiring or physical equipment.
Yes, it is necessary to use wiring and physical equipment such as telephone plants.
The expansion of simultaneous channels and extensions is immediate.
The expansion of channels and extensions is very slow, and in some cases the addition of new equipment is required.
Implementation time can be a matter of hours depending on the solution.
Implementation time depends on many factors such as the delivery of the trunk by the telephony operator, and could take several days to implement.
Multiple devices such as PCs, Tablets, Smartphones, and IP phones can be used for operation.
Only analog phones can be used to start operation.
Integration with third-party functionalities or different devices is possible.
There is no way to integrate with other solutions because there are no APIs.
