Using the Speakerphone Feature

Your modem is shipped with software that makes it easy to use
the speaker and microphone for hands-free phone conversations.
In addition, certain features can be controlled using AT
commands, although we do not recommend that the average user
do so. If you would like to control the speakerphone feature using
AT commands while in terminal mode, further information is
provided in Appendix D.
To use the speakerphone feature of the modem, be sure that the
microphone and speaker are plugged into the jacks on the rear of
the modem. Then see your software documentation for
instructions on how to enter speakerphone mode and use
the speakerphone feature.
Some things to note while using the Speakerphone
feature:
The speakerphone feature is full duplex, which means that
parties on both ends of the conversation can talk
simultaneously. This may not be possible at all times,
however. Under certain circumstances—for example, during
satellite-based international calls—the speakerphone may fall
back to half-duplex mode. You might also experience periods
