server proxy is used to transcode between G.729/ADPCM and G.711. Since the media
server proxy is a switch resource, there are a limited number of G.729 proxies. If there are
insufficient G.729 proxies, then ADPCM is used instead.
Figure 3-3 shows the switch-to-switch call control and media communications flows.
For more information on ShoreTel’s SIP-based call control, see Section 2.3.1.1 on page 8.
3.1.6 Integrated Server Applications
There are several integrated TAPI applications running on the server. These applications
use TAPI to send and receive call control information, and can also manipulate calls. These
applications also use ZIN Manager and DCOM to access and update the configuration
database.
3.1.6.1 Voice Mail
Voice mail is a TAPI application that supports 254 simultaneous voice mail or Auto-
Attendant connections. The voice mail system uses SMTP to transport composed messages
between the distributed servers. Media streams to voice mail use RTP packets to send
media.
Voice messages are stored on the server’s hard drive in the VMS MESSAGE subdirectory of
the Shoreline Data directory. Voice mail messages are stored as .wav files. To help you
calculate storage requirements, one hour of messages requires approximately 28.8 MB of
disk space.
