Why You Should Move from POTs to VoIP?

Voice Over Internet Protocol(VoIP)The migration from POTs into newer VoIP technology can be achieved successfully by using SD-WAN, which ensures the quality of experience right from the customer’s network to the voice service provider’s network.

FREMONT, CA: Voice over Internet Protocol (VoIP) has radically transformed the communication services in the past few decades. It provides various advantages over the legacy-based plain old telephone service (POTs) such as better quality of services, features, integration with other business processes, and ease of service management.

According to an FCC report, about 65 million users switched access lines in service and 59 million opted for interconnected VoIP subscriptions in the U.S. POTs network has physical connectivity up to the end user premise while VoIP technology utilizes an internet network for communication. Despite the clear advantages, enterprises in the U.S. have been reluctant in switching from POTs to VoIP connections.

Some businesses are concerned over the effectiveness of a VoIP system where the data packets compete with other data traffic in the same circuit. Here are some of the challenges while migrating from POTs to a VoIP technology and how software-defined wide area Network (SD-WAN) is providing answers to the challenges:

VoIP Design and SD-WAN

SD-WAN significantly boosted the quality-of-experience by incorporating a virtual encrypted pipe between the service providers and the end users. It allows the end users with multiple internet circuits for redundancy where the voice calls can navigate across the circuit, enabling enhanced performance. Further, virtual overlay with encryption tunneling allows the end user with direct connectivity to the service provider.

Machine-to-Machine Use of POTs Lines

It’s essential to note that POTs lines are also used for services like alarm systems, swimming pool emergency lines, gate/door openers, and elevator phone lines. Though VoIP providers provide off-the-shelf analog telephone adapter-based VoIP solution, it’s challenging for them to handle machine-to-machine (MTM) communication systems such as gate openers and alarm devices.

Business Process Change Issue

Several businesses still use POTs-based systems. Key systems refer to specialized phones with multiple lights and buttons to signal line in use. Small companies often use these systems as it provides them with features such as park and retrieves, the convenience to place calls on hold, and use intercoms and paging functions.
