Volume Persistence <volume/>
The user’s selection of the receive volume during a call can be remembered
between calls. This can be configured per termination (handset, headset and
hands-free/chassis). In some countries regulations exist which dictate that
receive volume should be reset to nominal at the start of each call on handset
and headset.
Gains <gain/>
The default gain settings have been carefully adjusted to comply with the
TIA-810-A digital telephony standard.
