Voip connectivity across branches and home offices


More than 30% of all businesses use VoIP systems. The Global VoIP market share is expected to reach $55 billion by 2025. Although the biggest spurt in growth was up to 2012, it remains growing steadily to this day, and not without a reason. It is a cost-efficient and convenient way for a business to set up communication with other VoIP or landline users via the internet. It is expected that small to mid-size businesses will find VoIP especially attractive in the coming years due to smaller costs of implementation and remote work trends.


The use of VoIP technology is growing due to its’ many benefits. One of them is flexibility due to the variety of devices and platforms users can use to place calls from, like IP phones, handsets, desktop phones, mobile apps, and so on. It also gives more mobility, since this method does not require to have a landline and works with an internet connection that is much more widespread. This becomes especially relevant now with the rising demand for remote work. It would be difficult to provide a landline to each employee working from home, whereas the internet connection is usually present in every household.

However, there are certain challenges to consider regarding the VoIP system. VoIP requires a broadband connection with high-data throughput, otherwise, the call quality may suffer. Outdated equipment might also have negative effects. The right networking products are essential to achieve maximum results and ensure security. VPN data encryption and Firewall are a must-have to keep the business conversations private and confidential information safe.
