While I am not new to the PBX/VoIP scene, I am new to asterisk just discovering this earlier today. I am planning on implimenting an asterisk system in my office for my business to test and possibly deploy and or recommend to our clients. I have just downloaded version 1.3 and read the documentation about needing FXO and FXS pci cards. I have found several of the Wildcard X100P cards on eBay for cheap. Before I buy these, I noticed that they are FXO but don’t mention anything about FXS cards? Since my goal is to use internal VoIP but external analog phones, I assume I will need a new X100P card for each outside line I use? Do I need any FXS cards with that? Or is FXS supported in the X100P?
Thanks for all of your help.
