Description
Select the Codecs in the order in which you want the system to
attempt to use them.
Performance note: Codecs on all networked BCMs must be
consistent to ensure that interacting features such as Transfer
and Conference work correctly.
Systems running BCM 3.5 or later software allow codec
negotiation and renegotiation to accommodate inconsistencies in
Codec settings over VoIP trunks.
Note: The G.723 codec can be used between IP endpoints. If
other types of connections are required, ensure one of the other
codecs is also selected.
