Analog PABX Intercom

[atif.kamal]

I want to setup a intercom system of around 210 nodes, analog pbx is available in market but i want to use computerize pbx such as 3cx or asterisks but i want to use normal analog (rj11) telephone sets as extensions. FXS/FXO cards as used with asterisk by digium are so expensive and have limited ports for legacy extenstions.

Any one of can tell me how to cope with this issue, which hardware/card is availble for above solution.

Thanks in advance

Its best to use SIP phones, not analog phones.

If you insist on using analog phones, you will need to get FXS gateways (not asterisk ones, those only work on linux and with asterisk), but they are definitely quite expensive. If you want cheap you are going to have to use soft phones.
