After delving into various forums and doing a lot of searching on Google, I’ve managed to confuse myself as to how to deploy Asterisk in a small office setting.
Here’s the situation:
Three (3) incoming plain old regular analog phone lines coming into the office from the telco;
Ten (10) phones within the office itself (to dialout/utilize 3 analog lines).
Although I assume I need an FXO card that can handle the three incoming analog lines, I’m confused about the office side of the equation.
Can I use something like the Wildcard TDM400P – with three (3) FXO modules (for the 3 analog lines coming in) and one (1) FXS module to handle the 10 office-side phones (the 10 SIP phones would be connected to a switch or router which in turn would connect to the TDM400P)?
It’s the office-side of the equation that has me confused.
What’s the best way to connect 10 phones to the Asterisk server? Although I haven’t made up my mind, I’m thinking of deploying the Grandstream GXP-2000 phones (10 of them).
