My office have just purchased second hand asterisk appliance synway SCU03 (synway.net/prds.asp?id=359) from an out of business establishment. We were hoping to replace our traditional PBX into asterisk PBX system of 5 analog phone, and 2 POTS lines
The problem is, when I checked the configuration in the SCU03 appliance, it have only FXO modules in it (12 ports to be exact) and no FXS. And our office have about 5 analog phone lines to serve and only 2 POTS.
Now the solution obviously is to buy some FXS modules and install it to the appliance, or to buy 5 x IP phones. However, the cost to do that will be quite high.
So the question is: what other alternatives I can do to integrate those 5 analog phones into the system without breaking the budget. (ie. what is the cheapest alternatives I have to solve my problem)
Many thanks in advance.
