1. Introduction
The FreiTel-IP handsfree telephone system consists of a SIP endpoint which can control up to
three speakerphones. This product is intended for use in environments where a handset and
keypad are not required, such as elevators.
The speakerphone is a surface-mounted unit which has a user interface which consists of a
button, two LEDs (green and yellow), and a microphone/speaker. Pressing the speakerphone
button causes a call to be made to a preconfigured telephone number, which can be terminated
only by the called party. The green LED on the speakerphone remains on while a call is active.
The FreiTel-IP can be configured to accept calls automatically or manually. If configured for
automatic call acceptance, every incoming call is accepted automatically without delay, and
remains active (indicated by the green LED being on) until terminated by the calling party. If the
unit is configured for manual call acceptance, an incoming call is signaled by the yellow light
and can be answered by pushing and holding the speakerphone button, which turns the yellow
LED off and the green LED on. A manually accepted call remains active until terminated by
releasing the speakerphone button, which turns off the green LED.
FreiTel-IP can be configured to filter incoming calls so unwanted calls are ignored.
The control unit has an Ethernet connector and a single multicolored LED. If attached to an
Ethernet network, the LED turns red until the controller registers with a SIP proxy, at which time
the LED turns green.
The configuration used for testing consisted of a TAS FreiTel-IP control unit and a single
speakerphone together with a pair of Avaya S8720 Server running Avaya Communication
Manager, Avaya G650 Media Gateway, Avaya SIP Enablement Services (SES) server, and
various Avaya telephones. Note that the SES server is a combined home/edge configuration
