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? Conrad
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.

I would look at the cost of the channle banks vs. selling the analog phones and getting very basic voip hardphones. --- Conrad Wood <asterisk-users@conradwood.net> wrote:> 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.

Conrad, i would go with following solution: 1. 6 sets of Audio Codes of 24 FXS ports conected by SIP accounts to the system. the type is MP 124. then you open the conector on the initial MDF and then the users have the same phone on their table 2. one dual Xeon system (or even stronger - 2 Dual Core system). such a configuration can take 60 calls at g711. 3. 16 IP phones for the medium up users i hope i helped you in a way.
