SIP TRUNKS...
If, after considering new technology, you are not ready to implement a totally new solution, or if you already have newer telephone system equipment, we hope that you will consider SIP trunks to reduce the ongoing cost of your local service.
Most new systems can support SIP trunks, which can also be delivered as ‘analog’ lines to work with older phone systems as well.

A CLOUD-BASED SOLUTION BEST MEETS THE NEEDS OF SOME BUSINESSES. RATHER THAN CONNECTING IP PHONES TO AN ON-PREMISE IP PHONE SYSTEM, THEY ARE CONNECTED THROUGH AN INTERNET CONNECTION TO A CLOUD BASED PROVIDER.
From the desk phone, softphone, or any mobile device, ESI's eCloud PBX Hosted service delivers a single user experience across all devices. We are available to help our customers who could benefit from such technology.
ESI phones are built specifically to work with their eCloud Hosted solution making it the most integrated solution on the market.

ESI's eSIP IP on-premise phone system provides enhanced features, support for remote users and greater administrative control over your system. We can merge the enhanced capabilities of an on-premise IP phone system with cost savings offered by cloud-based SIP trunks to reduce your local service costs.
If you are still under contract for your local phone service (dial tone) and not ready for SIP trunks, the on-premise IP systems we provide can support analog phone lines until you are ready to make a change.
