Remote Ip Phones
ESI now offers the ability to connect telephone stations in any location anywhere in the world. Imagine sitting in a branch office in St. Louis or Seattle, using a phone that is an actual extension from your home office in Dallas.
For businesses that need more than just an extension outside of headquarters, our technology can connect the ESI phone systems (and, with the appropriate hardware, even non-ESI phone systems) at up to 100 branch offices. These multiple branch offices, as well as remote users, instantly communicate together, effectively creating one large system. As a result, each of these individual locations offers virtually all of the same features as the extensions sitting in the main office, without distance limitations. Additionally, each of the phone systems can function independently, taking full advantage of ESI's unique, robust features.
The future is now. Imagine the possibilities - and then let your imagination become reality.
