Voice CODEC Priority 1st–4th
Specifies the type of CODEC for voice communications.
Choose the appropriate CODEC for the network environment

When using multiple CODECs, set them in an appropriate
priority order.
Prior to establishing a call, a negotiation takes place over the
network and the CODEC to be used will be decided
depending on the setting of this parameter.
For details about relations between bandwidth and CODEC,
refer to "Detailed Explanations" in "2.2.3 Voice
Communication Parameters".

When the Fast Connect feature (see under "Others"
