Discover the best IP telephony solution for your business, easy to install and use.
¿Qué es la telefonía IP?
IP telephony is a telephone communications service that uses the Internet Protocol (IP) to transmit voice and data over the Internet instead of using traditional telephone lines. This telephony communicates by digital means through the network using VOIP or Voice IP, and has become the most used communication service by most companies in the world due to its low implementation cost and quality.
How does IP Telephony work?
Digital Process
The operation process of IP telephony is relatively simple. When we make a call, our voice is converted into digital data that is compressed and sent in packets over the internet or through a local IP network between IP phones from a telephone exchange. These packets are transmitted through routers and servers until they reach the call recipient.
Once the packets reach the recipient, they are decompressed and converted back into voice signals so that the receiver can hear our voice clearly. This entire process occurs in real time, allowing fluid communication without noticeable delays.
Advanced Features
This cloud-based telephony offers many improved features compared to analog telephone systems, this is because the service is provided through the internet and can be managed from a web panel where you can review statistical data, upload contacts, add numbers, or adjust settings for remote and physical extensions, to take advantage of functionalities such as call forwarding, transfers, conferences, among others. Thus the company and users can communicate more efficiently, achieving improvements in productivity and saving costs.

What are the benefits of IP Telephony for Businesses?
IP telephony offers great benefits to companies by being a more economical, flexible and versatile alternative to traditional telephony, allowing your business to improve efficiency and productivity in internal and external communications. For example, it allows you to make national and international calls at much cheaper prices; it is highly scalable, which means it can easily adapt to the changing needs of a business.
It is possible to add or remove telephone lines as needed, without having to make physical changes to the infrastructure. With IP telephony, voice channels are transmitted over the internet and can be interconnected through a SIP trunk from a VoIP provider with a Virtual telephone exchange without the need for physical lines, providing the ability to receive and make multiple simultaneous calls with a single number, from multiple devices and from anywhere, improving mobility and remote work.
In addition, IP-based solutions typically have a centralized management interface that facilitates the configuration, monitoring and maintenance of telephone lines and associated functionalities, thus allowing centralization of the management of company communications from anywhere.

What is needed to use IP telephony in companies?
Having good telephone communication is essential for the success of any company. That is why more and more companies are adopting IP telephony, which offers higher sound quality, greater flexibility and reduced communication costs. But what is needed to use IP telephony in companies? We explain it to you below:
1
Requisito 01
A good Internet service
A good Internet service
The internet connection must be stable and is a high priority point to set up IP telephony, since it is a service that requires internet to function. It can be a broadband internet connection, with fiber, 4G, 5G, or satellite, the important thing is that it is high speed and quality, and has the capacity to cover all users of the same network.

Requisito 02
IP Terminals
IP Terminals
IP telephony allows the use of multiple devices for extensions or terminals that will fulfill the function of managing calls in the telephone exchange or PBX in the cloud. Below we define the most common devices needed to use this type of service:
IP Phones:
They are physical devices very similar to conventional landline phones but with the characteristic of allowing communication via the internet. In a cloud telephony system, IP phones connect to an internet modem or router to transmit voice over the internet. Some companies use it traditionally, but today it is replaced by VoIP software or softphones that have the same functionalities without the money investment in these devices.
ATA Adapters:
They are small devices that connect to the telephone line and the internet network to convert analog signals into digital ones. In this way, they allow you to use conventional phones to make calls through the IP telephony network.
Softphone:
It is an application or software based on the SIP protocol that can be installed on physical devices such as PCs, smartphones, and tablets. This App simulates or has the same functionalities as a conventional phone, therefore it is used to make and receive calls.

Differences between IP Telephony and traditional telephony
The most important difference between these two technologies is the savings. IP telephony has the advantage of being stored in the cloud and therefore it is not necessary to use wired, 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.

Preguntas Frecuentes
Resuelve dudas comunes sobre Telefonía IP y cómo funciona en tu empresa.
¿Cómo debería ser un sistema de telefonía IP ideal?
Un sistema de Telefonía IP realmente eficaz debe:
- Estar alojado en la nube, lo que elimina gastos de infraestructura física y posibles fallas técnicas a largo plazo.
- Ser escalable, para adaptarse fácilmente al crecimiento de tu compañía.
- Garantizar seguridad en todas las comunicaciones mediante protocolos de cifrado robustos.
- Ser intuitivo y fácil de usar desde cualquier dispositivo (laptop, smartphone, softphone, etc.).
- Contar con herramientas avanzadas (cola de llamadas, grabación, IVR, reportes detallados).
- Disponer de soporte técnico ágil y confiable.
¿Cómo es la calidad del sonido con la telefonía IP?
La calidad depende directamente de tu conexión a Internet. Con un ancho de banda estable y suficiente (mínimo recomendado: 100 kbps por llamada simultánea), la calidad de audio es equivalente o superior a la de la telefonía tradicional. Nuestra plataforma usa códecs de alta compresión y baja latencia para garantizar claridad en cada conversación.
¿Son gratis las llamadas realizadas por telefonía IP?
No exactamente. Aunque las llamadas internas (entre extensiones del mismo sistema) suelen ser sin costo adicional, las llamadas hacia números fijos o móviles sí tienen tarifa. Sin embargo, estas tarifas son mucho más económicas que las de la telefonía convencional, especialmente en llamadas internacionales o de larga distancia.
¿Son seguras las llamadas por telefonía IP?
Sí. Los sistemas de Telefonía IP modernos implementan protocolos de cifrado como TLS (Transport Layer Security) y SRTP (Secure Real-time Transport Protocol). Esto garantiza que tanto la señalización de las llamadas como el audio transmitido viajan protegidos, evitando escuchas no autorizadas o ataques de interceptación.
¿Qué importancia tiene la telefonía IP en un PBX Virtual?
La Telefonía IP es el núcleo de un PBX Virtual. Sin ella, no sería posible enrutar llamadas a través de Internet ni beneficiarse de funcionalidades avanzadas (IVR, grabación, informes, etc.). Además, el uso de troncales SIP te permite conectar tu PBX Virtual a la red telefónica pública (PSTN) a costos muy bajos, sin depender de líneas físicas tradicionales.
¿Necesito comprar equipo físico para poner en marcha el servicio de telefonía IP?
No necesariamente. Nuestro servicio de Telefonía IP es 100% en la nube, por lo que puedes empezar a usarlo sin inversión en hardware especializado.
Lo único que necesitas es un dispositivo conectado a Internet: puede ser tu computadora de escritorio, tu laptop, un smartphone o una tableta. Desde ahí, instalas un "softphone" (aplicación de teléfono por software) y listo: ya puedes realizar y recibir llamadas de inmediato.
Si prefieres la comodidad de un teléfono físico (con teclado y auricular tradicional), también existen teléfonos IP que se conectan directamente a tu red y funcionan igual de bien. Pero es una opción personal, no un requisito obligatorio.
