How to modernize telephony infrastructure without a large initial investment

Today’s technology allows companies, regardless of their size, to increase their productivity and profits. Among the most proactive actions that can be taken in this regard is to modernize your telephony infrastructure.

With a planned investment in solutions that optimize technological processes, the possibility of adding VoIP resources can have a direct impact on the bottom line of a small business.


Accessible technology

VoIP technology, which makes it possible to transport voice signals through a data network, provides greater mobility and agility in communication.

In a small business environment, when contracting for a VoIP link from a telephony carrier, the client has the opportunity to continue using an analog infrastructure while enjoying the use of functions that are only provided by VoIP technology.

“In the context of a small business environment, implementation of a VoIP link creates the need for at least an ATA, a device that can convert an SIP signal for an already existing analog infrastructure,” relates Lucas Melo, a product developer at Khomp.

This way, the analog-digital converter makes it possible to modernize telephony infrastructure without a costly initial investment.


Why should I be concerned with this?

According to data from the portal Terra, the adoption of voice over Internet services can represent savings of up to 70% in the cost of telephone usage.

“The small businessman can contract for a VoIP link from a telephony carrier and, with the use of an ATA, maintain the analog structure at his company with a low-cost investment that provides a quick return for the client,” explains Melo.

Another interesting alternative is to take advantage of an ATA to make use of the functionalities of an IP PBX. “In this case, the topology is the following: the SIP signal leaves the carrier, passes through the IP PBX, which talks to the digital converter that translates the signal to analog for use within the companies system,” he explains.


Gateways and ATAs

As opposed to ATAs, which only convert the VoIP signal to FXS, gateways interconnect a variety of technology scenarios. This equipment is designed to substitute a single device for various signaling and connectivity devices.

This means that it is possible to capture the SIP signal directly from the ports of a gateway, and distribute it as an analog signal within the internal structure via FXS; or digitally, via E1. To say nothing of the ability to make the conversion to a GSM signal for low-cost cellular calls possible.

The choice of one of these technologies will depend on the needs of the client’s business, not its size. This means that it is necessary to consider which types of interfaces the company needs at the time it is modernizing its telephony system.

“The question that needs to be taken into account with this choice is the cost benefit and the organization’s requirements. For example, depending on the carrier’s link, the gateway makes it possible to forward the call to as many signals as you want. Thus, it has greater reach and coverage,” he explains.
