Avaya Expanded Meet-me Conferencing Server
Issue 6 February 2007 99
On an S8300 Media Server running Communication Manager, the internal Voice over IP (VoIP)
resources enable the S8300 Media Server to communicate with the EMMC Server. For an
S8500 or S8700-series Media Server running Communication Manager, the port network
connected to the EMMC Server must have the following:
● At least one TN2302AP IP Media Processor or TN2602AP IP Media Resource 320 circuit
pack for IP/TDM voice processing.
The EMMC application supports only G.711 codec (both A-law and Mu-law), which means
Communication Manager software must do the conversion. When TN2302AP is used,
firmware vintage 72 and greater is required for RFC2833 for transport of DTMF as in the
SIP case.
● At least one TN799DP C-LAN circuit pack for the signaling links between the
Communication Manager server and the EMMC Server.
Architecture
An example of the EMMC architecture is shown in Figure 19.
Note:
Note: The EMMC feature does not require SES for SIP trunking. SES is an optional
service if SIP endpoints also will use Expanded Meet-me Conferencing. SES
cannot communicate with the EMMC Server directly. SES must establish all
conference calls via the Communication Manager server.
