[Asterisk-Users] Asterisk as Internet Talk Radio PBX system

[Stefan de Konink]

To use Asterisk as platform for such a system you probably want to have a
Alsa enabled card which supports routing of multiple channels in and out.
So Asterisk is like the intermediate 'engine' that routes the signal. (Or
sort some soft-mixer). A user is then placed in a Meetme room and the
hold signal would be the live show?

Technical picks of the phone by prelistening, transfers it to a new or
existing meetme. When the actual 'meeting' starts, the meetme gets in the
air studio audio (presenter) gets in by the Alsa interface.

Somebody earlier suggested Asterisk for use in remote broadcasts (on a
location for example). With two boxes and a ISDN line on both sides, some
encoding and you are in business too.

Asterisk as a application platform is quite powerfull, but probably has
some overhead which 'all-in-one' products have.
