ONE INTERFACE, 2 NUMBERS: A dialer app + a messaging app that work with your existing carrier service number and a 2nd number that Mast provides, all in one simple, familiar interface.

LOCAL NUMBER: Select the area code of your second number whether in the USA or Canada

NUMBER PORTING: Already have a 2nd number or a work number? Bring it to Mast as your 2nd number and get rid of that old landline.

CARRIER RELIABILITY: Most calling apps only work over Wi-Fi or 4G. Mast uses your existing cellular network which makes Mast calls the same great quality you get from your current phone calls.

MAKE CALLS FROM YOUR DESKTOP: Make and receive calls from your desktop using the same numbers you have on your phone - whether on Windows or Mac.

PRIVACY: Your personal phone numbers are part of your identity. Having a 2nd number and one easy app to manage both means you can choose who has access to you when. Turn off notifications and calls from your 2nd number on the flip of a switch in the Mast app.

FREE CALLS & TEXTS (USA & CANADA): Texting and Calling to the USA & Canada is Free and Unlimited. Calls simply use your existing carrier minutes to the USA (which are probably unlimited). International calls also supported.

TWO SMART VOICEMAILS: Set two greetings - one for your current phone number and one for your 2nd number. Sound more professional and keep your work and personal voicemails separate. Get your voicemails as text in Mast and in email so you can listen offline.

SALESFORCE INTEGRATION: Use Salesforce or Dynamics? Access your contacts and leads from Mast. Mast automatically logs calls you make and receive on the 2nd number so you can focus on closing deals not typing in data. It even rolls up texts as conversations and logs those. Then finish it up by adding a note easily without having to jump back and forth into a CRM app.

CONFERENCE CALLS: Find it a pain to dial into conference calls? So did we until we built the smart conference call number recognizer. Now joining conference calls are 1 tap away - and we log them into Salesforce with all the right attendees automatically!

HOW IT WORKS: Mast knows about both your numbers. You can choose to make regular calls or Mast 2nd number calls by contact. Mark your family as personal and your customers as work and Mast does the right thing. When you get calls from new numbers you see if its a call on Mast or not so you know how to answer your phone.

TEAMS: Every account on Mast automatically is a team. Turn employee phones into your company phone system. Own and keep your business phone numbers even as employees come and go. This is the simple answer to BYOD.
