This topic is serious and something more people should know about. Take it from me I know all about these services. It's in my field of work. You see I work at somewhat of a small company but we have to deal with a lot of customers over the phone. We have been using https://hottelecom.biz/ and it has proven to be the winner. With them, you can choose cloud phone systems for numbers of more than 100+ countries. That in its self is truly amazing. I could now easily transfer incoming calls to my employees anywhere in the world.
