[Asterisk-Users] Announcement only Devices that work with Asterisk for Dedicated 24/7 Conferencing

[Rusty Dekema]

Huh?

I think the original poster might be talking about the opposite of what you
are talking about. I understood him to mean that he wants a device that
stays connected to an Asterisk extension and plays any audio received over
the connection through a loudspeaker. I don't see how a cassette player
comes into this at all.

Following along the lines of the previous suggestion, you could use an ATA
in Hotline mode with an analog speakerphone, but the phone would have to be
designed in such a manner that it if it were hung up upon or disconnected
from the ATA, it would go right back off-hook and directly into speakerphone
mode without intervention. I do not know of any analog speakerphones that
will do this, but someone else might.

Unfortunately, I also do not know of any SIP or IAX products that would do
this out of the box. However, it would be very easy to modify an open-source
SIP or IAX softphone to do what you want. However, that may or may not be
practical for your situation. If you really want this in a small "appliance"
form factor, you could probably design and build a device that would run a
softphone on an embedded CPU, but I suspect that even Morgan Stanley's IT
department might not want to get into that scene :).
