21 * \brief DAHDI for Pseudo TDM
23 * \author Mark Spencer <markster@digium.com>
25 * Connects to the DAHDI telephony library as well as
26 * libpri. Libpri is optional and needed only if you are
27 * going to use ISDN connections.
29 * You need to install libraries before you attempt to compile
30 * and install the DAHDI channel.
33 * \arg \ref Config_dahdi
35 * \ingroup channel_drivers
37 * \todo Deprecate the "musiconhold" configuration option post 1.4
