TELEPHONE SYSTEMS Telephone service is an integral part of any size business. The IT4 can help you customize a phone system that is both affordable and flexible enough to meet all of your needs. If you need two phones and two lines with an intercom in a small office, we can purchase and install the phones, and instruct you on their use. If it is 200 phones with 25 lines in a large office building, we can configure and order the phones and equipment that is right for you. The IT4 can also help you choose the service that is right for you. We can save you money by bundling internet and telephone service; even if you already have the phone equipment; let us evaluate your service to save you some money. We offer complete telephony service from wiring to voice mail setup to end user training.
