Volume Persistence
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
The default gain settings have been carefully adjusted to comply with the
TIA-810-A digital telephony standard.
