Most VoIP providers only provide 1 line in and out for 1 phone number. When your company needs multiple lines in and out, you have to buy more telephone numbers or lines, and each telephone number or line will cost you.

Every phone number in the Extension-N VoIP contains 10 lines (in and out), which means 10 extensions can communicate with other different companies or individuals at the same time. And the cost per 10 lines for 1 phone number is only $3.99 per month.
