One of the most popular ways for businesses with multiple branches to make announcements is through the use of  free conference calls . This allows important information to be relayed immediately and also allows on the spot responses from participants as well as questions from the same. This will of course save the company the expense of having to spend for the transportation and accommodation of all the participants involved in a call. The participants will also need to spend minimal time away from their other important tasks, resulting in better productivity.
