Using the telephone
Voice messages can be played back and recorded using the telephone.
Playing back voice
messages When playing back a voice message, the message is moved from the
Exchange server to a telephone via the voice server. The playback is not
affected by the speed of the client network connection. However, if
playback controls are used, for example, fast forward or rewind, these are
routed through the network connection. Playback controls occupy little
bandwidth, so they are only slightly affected by a slow network
connection.
