I’m having difficulty understanding what hardware (Analog card in particular) I would need to install to interface with my current phone system.
I have used asterisk in the past but is was an all-IP set-up. My current scenario is two analog phone lines (AT&T) one of these is also a DSL line. the lines roll over so if a call is received one one while the other is busy the free line rings. we currently use 3 analog (2-line) business style (Panasonic KX-TS3282B) phones. our primary goal for using an Asterisk box is to handle voice-mail, call recording, and call tracking.
My understanding is that I would need an analog card with 2x FXO Ports (to attach to the incoming phone lines) and (at least) 2x FSX ports (attached to the phones). Is this correct? and if so how would DSL be affected? would the Asterisk box have to be installed after the DSL modem, Would a DSL Filter need to be used? If so where?
Any recommendations,and/or clarification would be greatly appreciated. We would like to keep this as simple and low-cost as possible. We have 11 other locations all containing 5 analog lines (one being FAX/Credit Card machine and one being Voice/DSL) each that we would like to set up PBX’s also. But would like to get a better understanding of what I’m doing on this small scale project first. Thanks
