Might be a bit of a tangent: use SIP at home via internet
I use a SIP provider for the landline at home. When on vacation I want to be able to make outbound calls with my landline number. I know this can be done, but I have no idea how. Does anyone here have some pointers for required hardware, software and configuration?
I have Ms VoIP as my provider. $1 month per line and 1 cent per min.
I have a grand stream sip adapter... Configured with my providers info and my creds. Phone can plug into it. Works just fine. Plus you can use any sip client to connect to the same line from mobile or PC.
Also, my old house had pots lines in every room. I took my grand stream and wired it into the house, not a phone. So I can plug regular phones into any of the original outlets and it works as it directly connected to the grand stream. I have 4 regular phones all running over original wires into the grandstream using sip
I've used them for well over a decade, I even sent the CEO an email when I had a CS rep telling me I couldn't do something I knew I could. He sorted it out within the hour.
Voip dot ms employs a ton of countermeasures versus skript kiddies as voip fraud is a severe problem. You are unlikely to have much luck with Tor Browser. I have to ask them to take my boring data center IP off their greylist every time I want to add cash to my balance.
I've long wanted a cheap way to setup a phone, when rung, picks up and plays a message telling the caller to email me. But everything I found for this is wayy more expensive than $12/yr
