[Asterisk-Users] Earpiece Connections

[Michael at matraex.com]

Does anyone know of a piece of hardware that can allow multiple earpices
to be connected directly to a server running Asterisk.
I hope I am not being to vague but basically I am looking to allow a
call center to user the server to do all of the "Pickup" and "Hangup"
functions.
The operators will merely have to have th earpiece in their ear.  I have
seen serial pieces of hardware that do this (41D switch matrix?)
But I need to find one that asterisk can use.  I will then build some
custom scripts to handle the "Pickup" and "Hangup" parts of it.

Anyway any ideas or websites I could research for this type of thing
would be most helpful.

Thanks
