NEC Quality and Dependability.  ESSI has never had an actual NEC phone system switch or control unit fail.  The phones have about a 2% failure rate that we consider an out of the box failure.  All and all you can depend on the NEC Phone System day after day year after year.

Network Integration has enabled ESSI to make sure all of our customers are happy day after day with the ability to log in and make the necessary changes our customers need quickly and easily.

SL1100 Voice Over IP provides IP phones that can connect remote offices and home offices to connect via an existing internet connection.  Softphones that are best used to connect users from a hotel or on vacation, as typical internet connections at a hotel do not allow the ability to connect multiple devices to an internet connection.  The Softphone is installed on a Window Laptop Computer, once the computer is connected to the internet the Softphone will connect to the phone system.  The problem here is some hotels are not aware and do not have ports open that allow a Softphone to connect.

SL1100 allows the ability to call into the system and make calls out of the phone system making the user seam like he or she is in the office.

Free Remote Phone System Programming

All Systems Include Lifetime Support and Training.
