Local Conference Configuration

The local conference requires a host phone to process the audio of all parties. Yealink phones support up to 3
parties (5 parties for CP935W/CP925/CP920/T42U/T43U/T53/T53W/T33P/T33G/T31P/T31G/T31/T30P/T30 phones,
10 partes for T46U/T48U/T53C/T54W/T57W) (including yourself) 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
