For conferences initiated through the phone's own menus, the B199 hosts the conference itself. It does not use the IP Office conference resources.

This affects the maximum number of participants as follows:

• • The phone supports conferences with up to 4 other participants. However the actual number depends on the codecs being used by those other participants.

  • Each codec has an assigned load value as listed below. If the addition of another participant would reach or exceed a total load of 100, the phone will not allow the additional participant and displays "Number of participants limited by quality settings.".

    Codec	Codec Weight
    G.711	20
    G.722/G.729	33
    Opus	50
