With Group Listen, a user can carry on a conversation using the handset or headset while allowing others nearby to listen to the person at the far end over the handsfree speaker. The handsfree microphone is disabled in Group Listen mode.
Group Listen should only be used in conjunction with the laws of the jurisdiction where the call is placed and/or the laws of the jurisdiction of the place being called. Mitel is not liable for misuse of this feature in a manner that does not conform with the applicable law (for example: laws involving wiretapping, eavesdropping, electronic surveillance, call recording etc.). Dealers should warn customers in writing that they are responsible for the use of this feature in accordance with the law, and that in many jurisdictions the party subject to the Group Listen feature must be made aware that the call in which they are engaged is not private.
The telephone must be off hook with the voice path connected to the handset or headset (it may be part of a conference call or on Hold by the far end party).
An Off-hook Voice Announce cannot be in progress.
While in Group Listen mode, the set volume control adjusts both the speaker volume and the handset volume together.
If the SPEAKER key is pressed or the handset is replaced while in Group Listen mode, the call becomes a normal two-way speaker call.
If the TRANS/CONF, TRADE, or HOLD key is pressed while in Group Listen mode, the call follows the associated call processing and Group Listen terminates.
Overrides will disable Group Listen if it is in use when the call arrives.
Incoming pages to a set in Group Listen mode are disallowed; the paging party receives busy tone.
The Microphone key is disabled while in Group Listen mode— that is, it cannot be used to re-enable the handsfree microphone.
