Communications technologies have rapidly advanced in recent years with the maturity of Voice over Internet
Protocol (VoIP), the strategy of software virtualization, and the birth of Unified Communications (UC).

For almost decades now, most hotels have relied on the hardware-heavy PBX phone systems for communications. These guests’ needs than traditional ones would require extensive wiring throughout the building, expensive reliance on phone companies, and the stress and difficulty of continuous system maintenance.

Since digital collaboration is known as an important part of any business, Voice Over Protocol has become indispensable. However, as it becomes popular, the threats against it become widespread too. With this, security must be a priority, particularly because cybersecurity and privacy risks continue to grow.

Internet telephony is quickly becoming the ideal option for most firms, owing to its increased reliability and accessibility. Two application layer protocols form the backbone for IP telephony, SIP and RTP.

PBX, which stands for Private Branch Exchange, is a telephony technology that has existed for a long time. It refers to a private telephone network used within an organization where users can communicate both internally (within the firm) and externally (with the rest of the outside world).
