At the Communication Center of Hawaii, we offer PBX, Key, and VOIP telephone systems, voice mail, and computer network wiring. Located on the Big Island of Hawaii, we can work throughout Hawaii. Communication Center is not locked into selling particular brands or models of telephones (as are many companies). We are recognized by a wide range of companies as being able to install and sell their telephone system. As a result, when you ask for a quotation for a new telephone system, we analyze the content of what your company offers to suit your needs.
