Page 505 - Asterisk™: The Future of Telephony

modem.conf

The modem.conf file is used by Asterisk to communicate with ISDN-BRI interfaces
through the ISDN4Linux driver. Since ISDN4Linux lacks many core ISDN features, it
is not generally used. For BRI, the most popular add-on seems to be chan_capi, available
from http://www.junghanns.net.

musiconhold.conf

The musiconhold.conf file is used to configure different classes of music and their lo-
cations for use in music-on-hold applications. Asterisk can play hold music in any
native file formats. Asterisk can also makes use of a certain version of mpg123 to play
MP3 files, but this is discouraged. You can specify arguments for a class, allowing you
to use an external application to stream music either locally or over a network.

osp.conf

The Open Settlement Protocol (OSP) is officially documented in ETSI TS 101 321, a
European Telecommunication Standards Institute (ETSI) document that came out of
the work of the TIPHON working group. As far as we can tell, OSP is another attempt
to apply old-style telecom thinking to disruptive technologies.

oss.conf

The oss.conf file is used to configure Asterisk to use the Open Sound System (OSS)
driver to allow communications with the sound card via the CONSOLE channel. Note
that ALSA is now the preferred interface for the CONSOLE channel.

phone.conf

The phone.conf file is used to configure a Quicknet PhoneJACK card. The PhoneJACK
card seems to provide something like an FXS interface, in that you can plug an analog
telephone into it and pass calls through Asterisk.

privacy.conf

The privacy.conf file is used to control the maximum number of tries a user has to enter
his 10-digit telephone number in the PrivacyManager() application. The
PrivacyManager() application determines if a Caller ID is set for the incoming call. The
user enters his 10-digit number within the number of tries configured in privacy.conf,
the application sets the PRIVACYMGRSTATUS channel variable to either SUCCESS or
FAILED. If the Caller ID is set, the application does nothing.
