What I need to do is record telephone calls that are made on regular phones on a regular telephone line, and record the calls somehow using a VoIP system.
I wish to use this system using a PBX and VoIP phone adapters without using an actual VoIP external line. The line that comes into my house is a POTS line. The setup does not look like it will work to me, but I have seen this exact setup where I work so I am very confident that it does work. I wish to do it like this:
Regular Phone ----> phone line splitter -----> VoIP Phone Adapter -----> PBX
|---> POTS line to outside
I am able to monitor calls right now using a SIP account on the PBX. But, I do not want to use anything but the regular POTS line I have do make external calls, and just record calls off of that. I am trying to explain this as best I can, so please ask questions. I do have a diagram to detail what I am trying to do and can get it to anyone who wants it. Thank you.
