I'm trying to receive a call from the PSTN network on Asterisk. I have a PSTN wall socket (POTS line, not PRI/BRI). Is there any adapter that I can use for this purpose (adapter will receive SS7 call, convert to SIP, and send it to my Asterisk server)?
I have a Linksys PAP2T Internet Phone Adapter but, after reading the documentation, I realized that this adapter was not meant to be connected directly to a PSTN wall socket.
To provide a bit of background:
I'm doing a project by myself at uni to do some filtering to stop spam/robot calls. I implement this on Asterisk dial plan and, at the moment, in a simulation environment (i.e. using VMs / softphones). I'd like to make my project more realistic by being able to receive a real-world PSTN call. I did read about Digium cards that process calls coming from PRI/BRI lines. However, for my purpose, I was hoping I wouldn't have to shell out around $100 to get those cards. Also, since those are PCI, I'm not sure how I can connect it to my laptop. Does anyone know if an adapter is sufficient and, if so, can you suggest an adapter?
Apologies if my question is a bit basic as I'm new to Asterisk (been a few weeks).
Also, on a side note, do I need DAHDI drivers to receive incoming PSTN calls? I had trouble installing them. It seems like the latest DAHDI driver (2.11.1) is incompatible/has issues with the latest Asterisk (14.3.0) and someone suggested, on a forum, to wait for the next release.
