Note:Please be aware that your phone line provider needs to be consulted on how to utilize the conference facility!
Analog phones, such as the Polycom SoundStations, have limited functionalities to enable/disable certain features on a PABX/PSTNLine.
Analog Line Basics
The phone itself does not hold the conference, as this is not a technical possibility.
The conference itself is held within the PABX/PSTN that provides the analog line, and this completely depends on the line being used.
The phones use the Conference / Join button to send a Flash signal to an analog line.
The Flash actually interrupts the phone line for a pre-defined duration and signals to the PABX/PSTN that a feature is requested.
NOTE: This functionality depends completely on the PABX/PSTN.
Typical Use of Flash
Usually, this is used to place the call on hold, and the PABX/PSTN will:
Provide a new dial tone
Enable the user to call another phone
Or retrieve the call from hold if pressed again
NOTE: Please be aware that a limitation may be that the analog line does not support a 2nd call. Please liaise with your PABX/PSTN provider.
Flash Time Settings
Most Polycom SoundStations offer a menu option that can change the Flash time.
A usual value, depending on the PABX/PSTN, would be:
75 ms
100 ms
300 ms
600 ms
Special Dial Codes
Certain PABX/PSTN require a * (star) or # (hash/pound) code, with or without additional numerical digits, to invoke the conference facility. These need to be manually dialed.
Provider Information
The information on how to join or split multiple calls must be provided or inquired from your PABX/PSTN line provider.
