Here’s my proposed architecture:
- 3 incoming analog phone lines
- 1 good server running asterix (or another IP PBX)
- 10 telephone stations
My question lies with how I connect the 3 analog phone lines to my Asterix box. I’m confused as to the devices out there:
I understand that manufacturers of “Analog Interface Devices” with 3-4 FXO cards from Digium, Sangoma, and Rhino can be put into the Asterix box and presto all should be good.
But what I would like to understand is how about using a “SIP Gateway”, such as the Mediatrix 1204 (http://www.mediatrix.com), AudioCodes MP-114 (http://www.audiocodes.com), or VegaStream 50 6x4 (http://www.vegastream.com). Can I use one of these “gateways”, even if they offer no additional benefit, instead of the “analog interface devices” above?
The reason I am interested in these products, is because I would like to evaluate 3 software PBX products (costs & operating systems aside):
- Asterix ,
- Objectworld’s UC Server (http://www.objectworld.com), and
- 3CX Phone System (http://www.3cx.com)
PBX #2 and #3 both list compatibility with the SIP Gateways and make no mention to the interface cards. So if I were to invest in purchasing one SIP Gateway to test all 3 of these products, would the SIP Gateway also work with Asterix? How about the other way around?
If I’m not making sense or am confusing myself, please feel free to let me know up front.
