Description:

ShoreTel Premises platform is an on-site IP PBX and unified communications (UC) service for the enterprise. The Premises platform has four main components: voice switches, IP phones, ShoreTel Director and ShoreTel Communicator.

• • The product's core is the ShoreTel Voice switch. These are devices that integrate voice functionality, communication, call routing, IP phone registration and SIP trunking or telecommunications provider termination (ISDN-PRI/PSTN) in one box.
  • The ShoreTel phone system has an interesting approach and, according to ShoreTel, its main advantage is simplified design, administration and high reliability. The ShoreTel phone system currently supports 14 different voice switches, each with its own characteristics, providing a wide range of deployment choices and telco connectivity capabilities.

ShoreTel Connect CLOUD is fully hosted and managed unified communications as a service (UCaaS). It’s the only end-to-end cloud business phone solution, from the phones and PBX capabilities to implementation and support— including direct user access to customer service via the “?” key on your ShoreTel IP 400 series desk phone.

Because we’re an end-to-end solution, your vendor management becomes easy. We replace separate telco, carrier and service providers. We’re your single point of contact for your call plans, phones, installation and customer support. An end-to-end solution means all the ShoreTel Connect CLOUD components are optimized for best call quality, and you never need to worry that a software upgrade will disrupt service or performance. No other cloud provider provides this level of product integration.

• • ShoreTel Director is a unified management tool that allows for administration, setup, diagnosis and reporting of all ShoreTel equipment. The software can automatically discover and configure any ShoreTel devices and supported services, including voice switches, IP phones, voicemail and call routing. ShoreTel Director is installed on either a dedicated server or virtualized platform and is managed via a Web interface. With ShoreTel's IP PBX solution, a voice switch can be connected at a remote branch and the administrator will immediately see and configure the new device through ShoreTel Director, regardless of physical location.

If the software's host server crashes, the whole ShoreTel infrastructure will continue to run and function without any interruptions.
