I want to interface asterisk with a legacy pbx that has around 23 extensions through my 8 fxs card, how do i work around this? Hint: I have already terminated 8 extensions from the legacy PBX, i was thinking whether i can peer the extensions from the PBX i.e like 5 extensions be peered to one extension connecting to the fxs? How can i do this?

Thanks in advance,

Are you planning to get rid of the legacy PBX completely? Or is Asterisk going to be a second PBX?

I am going to assume you are replacing the legacy PBX. You can setup analog extensions so that you have multiple phones on each FXS channel. But they will be like a party line. If you put 6 phones on one FXS, all 6 ring at the same time, only one person can use that extension at a time.

However you can add SIP phones to Asterisk and each can have their own extension instead. It just requires cat 5 cable back to a switch for each phone.

Just to add my 5 cents - connecting too many phones to an FXS port can cause problems. The term is REN - ring equivalent number, and it's used to describe the maximum phones to attach to an FSX port (from memory)
