I recently installed a wireless backhaul system for our internet connection to get off of satellite internet. At the site where our DSL connection is, we also have a phone line we’d like to get to the remote site as well. After it gets to the remote site, I’ll most likely want to convert it back to a normal phone signal for use with our older pbx system (we’ll switch to something more sophisticated in the future, don’t worry).
Where should I start with this? I imagine there are tutorials on the internet for a simple setup like this, but I haven’t been able to find them yet. I’m wanting to do this on embedded hardware since it won’t require anything really powerful (it’s just one phone line used occasionally). I’m reading a bit about asterisk on the raspberry pi, and it looks promising. Any suggestions on how to do this?
