Krispcall is a great little company helping big and small busineses
I've used Krispcall for about a month now and was able to port my number successfully. Kirpscall has great features to manage a business through multiple time zones, have multiple numbers for multiple countries, receive voicemail, text etc. The phone app can be a little slower to repond when I click on dial a number but I'm still navigating through all the features to maximize its use,
