asterisk users - Sep 2006 - ATA being used as a SIP Trunk to connect LegacyPbx to Main Asterisk Server

Hi all,

Do you think it could be an affordable solution using a two fxs ATA device
to connect an old legacy pbx (with few users) with a main asterisk server.


phones----analogue----SmallOfficeLegacyPBx----ATA-2FXS-----SIP------MainOffice
AsteriskServer

This way also I would use ATA device as a Trunk without requiring an
Asterisk server on every smalloffice and no need to buy many ATAs neither
VoiP hardphones.

Is this affordable or i'm missing already basic functions required for a
production system?

One item you will need to research and tends to create problems for 
people doing this is  line supervision.  In other words, disconnect 
supervision, answer supervision, etc, are often times not provided by 
legacy pbx's, and therefore the ATA may not recognize hangups, etc.
