Grandstream GRP 2600 Carrier Grade Series IP Phones.

While the demise of the desktop phone has been a popular topic for a few years now, it continues to be a staple of telephony and unified communications deployments. Even as cloud platforms with mobile and desktop apps become popular, the global IP desktop phone market continues to thrive. Desktop phones are central to the way many businesses operate and a familiar and reliable tool for staff. They are central to the way we’ve all become accustomed to communicating and provide the most reliable and dedicated portal for voice communication.

As a result, the modern IP phone is easier than ever to deploy while being packed with features that make them more useful than ever.

Maybe of most significance, the modern IP phone is simple to deploy and manage thanks to cloud provisioning and management platforms.

IP Phone deployments


Service Providers

Business service providers are one of the largest deployers of IP phones. Many offer packages that include IP phones and other SIP endpoints in order to provide turnkey solutions for business customers.


Enterprises & Large Businesses

A voice network is a critical part of any enterprise communication solution. As large organizations become more dispersed and require more mobility both in the office and remotely, IP phones that support mobility and provide next-generation tools to keep in touch will be in demand.


Small-to-Medium Businesses

SMBs rely more on voice than almost any other sector. Not only is SIP/VoIP an extremely cost-effective communication solution, but it now offers a platform to easily add video, surveillance, facility management, remote solutions and more.



Think about it - have you ever had a hotel room that did not have a phone in it? The answer should be no. Most countries have laws requiring all hotel rooms have phones in them. Not only that, they provide easy communication with guests, integrate with property management systems, and offer guest service.
