Description EMCC Parameter This parameter specifies the maximum audio bit rate for all EMCC calls, regardless of the region associated with the other party. The default value is 8 kbps (G.729). Note All participating EMCC clusters must specify the same value for the EMCC region max audio bit rate. EMCC Region Max Audio Bit Rate This parameter specifies the maximum video call bit rate for all EMCC video calls, regardless of the maximum video call bit rate of the region associated with the other party. The default value is 384. Valid values range from 0 to 8128. Note All participating EMCC clusters must specify the same value for the EMCC region max video call bit rate. EMCC Region Max Video Call Bit Rate (Includes Audio) This parameter specifies the link loss type between any EMCC phone and devices in any remote cluster. Note To allow two-way audio on EMCC calls, all participating EMCC clusters must use the same EMCC region link loss type. Based on the option that you choose, Cisco Unified Communications Manager attempts to use the optimal audio codec for the EMCC call while observing the configured EMCC region max audio bit rate. Valid values are the following: • Lossy—A link where some packet loss can or may occur, for example, DSL. • Low Loss—A link where low packet loss occurs, for example, T1. When you set this parameter to Lossy, Cisco Unified Communications Manager chooses the optimal codec within the limit that is set by the EMCC Region Max Audio Bit Rate, based on audio quality. Some packet loss will occur. When this parameter is set to Low Loss, Cisco Unified Communications Manager chooses the optimal codec within the limit that is set by the EMCC Region Max Audio Bit Rate, based on audio quality. Little or no packet loss will occur. The only difference in the audio codec preference ordering between the low loss and lossy options is that G.722 is preferred over Internet Speech Audio Codec (iSAC) when the link loss type is set as low loss, whereas iSAC is preferred over G.722 when the link loss type is set as lossy. The default value is Low Loss.
