Keap: Business Line CRM is a free app that provides a second phone number for small businesses to separate their personal number from their business calls. This app is designed for small businesses and offers a virtual number for easy SMS and call forwarding. With Keap, users can set up a dedicated business phone number and manage their business calls with ease.

One of the unique features of Keap is the ability to display caller ID, allowing users to differentiate between personal and business calls. Additionally, the app offers a snooze schedule to pause business line calls and SMS notifications while auto-replies keep leads engaged. Keap also allows for customization of voicemail greetings and automatically transcribes voicemails for faster response times.

Other features include a business card scanner, easy contact import, appointment scheduling, and the ability to accept payments. Keap is available in the U.S. and Canada only, making it a great option for small businesses in North America looking for a second phone number.
