I have a situation than i am unsure of how to solve and I am hoping the fine folks here may be able to point me in the correct direction.
I have a situation where the client has an old analog system onsite that usually works through ATT PRI connections. I need to find a way to connect a FreePBX Appliance to the old system through some kind of PRI connection to provide them some kind of trunk/connection out over SIP. Is that possible? I know there are cards that work with PRI but i was unsure if they worked in this kind of situation. Any ideas on hardware or a set-up that would work?
