parties (5 parties for CP920/T42U/T43U/T53/T53W phones, 10 partes for T46U/T48U/T54W/T57W) (including your-
self) in a local conference call.
Note: Codecs that can support 10-party conference: G722, G723, G726, G729, PCMA, PCMU, and iLBC; the Opus codec can
only support 5-party conference.
The following table lists the parameters you can use to configure the local conference.
