I like that it's easy for people in different locations or time zones, as well as those who are traveling abroad (or even just across town) can easily communicate with each other using this service! It also allows me to have multiple phone numbers all under one account so when someone calls my office number they're automatically transferred over to another extension if needed without having to answer any additional questions from them first.
The only thing about ace fones you need to be careful of is not going into an endless loop where its constantly ringing because there was no activity at the end of last call but i think thats pretty rare. We've been able to get everyone connected through our system which has made communication easier than ever before.
