Are you planning to put up a contact center or perhaps work with one? Are you looking into equipping your sales and support team with the best phone systems available, the kind they use in call centers?

Call centers are not just the agents and managers – although these people are a huge part of a successful one. Contact centers are also defined by the technologies they employ, particularly their phone systems.

Of course, when we say phone systems here, we don’t just mean the physical phone unit. A phone system is made up of several hardware, software and processes.

It facilitates basic call center functions, such as call routing and logging, agent desktop interface, multi-channel communications and predictive dialing. Integrations, such as CRM integration and Workforce Management, are also requisites at this point. Additional features, such as automated customer surveys, quality monitoring, multilingual customer support, knowledge management and analytics, are good to have too.

So, know more about the most-used phone systems by contact centers. See where the difference lies; and then understand what’s best for your team.
