I guess if I was going to do this I would either have a sip adapter at
each phone. Or have to * boxes. One is connected to the PRIs. Then
connected to that via an IAX2 trunk is another asterisk box that is full
of the 24 port FXO/FXS cards digium sells. You could expand this as much
as you want by adding more asterisk boxes with the 24 port FXO/FXS cards.

Does anyone have any recommendations on how to connect 160 analogue
phones to an asterisk PBX?
Background information:
A client wishes to replace their current PBX with a new VoIP system.
Currently they have 2 PRIs.
I intent to set up 2 asterisk PBXs with Debian GNU/Linux on raided
drives. These drives will be mounted only read-only to recover
gracefully from power-cycles. I am considering 2 ISDNGuards in front of
the machines.
More to the point: The client has 160 existing analogue telephones which
they don't really want to change right now, because a) they are very
cheap b) the users don't need to re-train.
I have thought of Rhino Channelbanks, but then realised I need to use 7
of them and connect each with a T1. I don't really want to run 7 T1 +
the 2 PRIs into one asterisk box for performance reasons.
Ideally, several 48-Port SIP->FXS channelbank woulds be ideal I
guess ;-). Does such thing exist? Or how do others do this?
