Infinity 5000 Series Introduction

E-MetroTel 5000 Series Phones

The E-MetroTel portfolio of Infinity 5000 Series phones provide a range of user-focused features to suited to a both large and small business environments and users - including the reception desk, supervisor positions, call center agents, and office workers.

The Infinity 5000 series phones can operate in two modes - XStim and SIP.  E-MetroTel strongly advises operating in the XStim mode to get the highest value out of these devices. for two primary reasons. First, in XStim mode the phones are directly communicating with the UCx software to deliver all of the latest Unified Communication capabilities of the UCx; features and functionality are continually being added to the call processing and the XStim protocol allows that functionality to delivered to the Infinity 5000 series phones whenever the UCx itself is updated. This is in contrast to the SIP functionality which is limited to the feature set of the standard SIP protocol, with limited new functionality which must be programmed for every telephone. Second, when the phones are configured for XStim functionality they are able to connect using the E-MetroTel Extensions license, versus the more expensive Universal Extension license required for any SIP devices.

Firmware Availability

The firmware for both modes of operation is distributed on the UCx, ensuring that the phones and the UCx software compatibility stay in locked step. In the firmware update documentation sections for each of the modes of operation, instructions are provided for downloading the firmware from either the local UCx or the E-MetroTel repositories. The primary source for these updates should always be the local UCx.

Note that the best way to ensure that the latest firmware is available for the Infinity 5000 series telephones is:

  1. Update your UCx software (see Software Update)
  2. Set your UCx to automatically update its software on a scheduled basis (see Automatic Software Updates)
  3. Install the infinity-fw-package on the UCx Server:
    • From the UCx Web Configuration Utility, navigate to System -> Updates -> Packages page.
    • Click on Show Filter button and search for the ucx-infinity-fw package.
    • Install the package.
    • Once the package is installed, the latest Infinitiy phone firmware files will be placed under the /tftproot directory. Any future UCx software updates will also update the phone firmware files.
