Figure 4 Trunk-based Voicemail Server

Line-based voicemail servers

Line-based voicemail servers cannot directly communicate with the

MCP network. A Line Gateway, also known as an analog station

gateway, is required for the MCP to interwork with a line-based

voicemail server.

Similar to interworking with trunk-based voicemail servers, an SMDI

terminal server is to exchange data between the MCP and the legacy

voicemail server. However, the SMDI links are used to both send and

receive data regarding the storage and retrieval of voicemail from the

line-based voicemail server to the MCP network. Figure 5 shows a

network view of the MCP interconnection with a line-based third-party

voicemail server.
