Hello
A call center is an office where a company's inbound calls are received or outbound calls are made. Call centers are increasingly popular in today's society, where many companies have centralized customer service and support functions. Call centers employ many staff in customer service, sales, and support functions.

Call centers are often large offices staffed with representatives who either make or receive phone calls. Depending on the size of the call center, a single office could have anywhere from a few dozen to hundreds of telephone staff. Depending on the needs of the company, call centers can make either incoming or outgoing calls.
Thanks
