Configuring a personal VoIP server
Configuring a personal VoIP server
You might be able to set up your own VoIP service using your existing landline number. Although it may seem old-fashioned, the cost will remain the same regardless of whether you choose to use it.
Yes, it's possible. You'll need around $300 for DAC/ADC gear and a server to operate it. Asterisk is an open-source VoIP platform that handles all your requirements.
You might consider using an Obihai and transfer your number to that platform.
3CX might be an option I haven't tested, but I recall seeing it while researching IP phone systems. It uses software-based technology.
They’ve mentioned using this tool with Google Voice, but I haven’t tried it myself. My ISP limits bandwidth for VoIP, so I don’t want to use it unless it saves me data. It seems to work most of the time.
For the server configuration I suggest FreePBX. Chris from crosstalk solutions has a YouTube series on installing FreePBX. Regarding your number, it would be best to check with your cable provider to see if they allow access via a SIP trunk (unlikely) or consider transferring it to a provider that supports it.
