Our international partner, whose personnel are working in different time zones all around the globe, came to our UK office with a problem. To avoid wasting time and money for international calls, he needed to provide communication within all branches, located in 15 different cities, on four continents, with cross-company phone lines.
Each of the branches has its own set of local phone numbers, which should be used for the calls within the corporation worldwide. Additionally, incoming calls should be redirected to any of the 15 offices without delay, with a stable connection, and at local tariffs.
