i currently use optimum voice (cablevison) who has provided a Motorola sbv4200 voip cable modem. I have this extended to an analog phone. I want to use asterisk at home and I am unsure of what I will need.
Can I just extend the line from the modem into an external sip capable Analog adapter of some kind? And then use a sip based softphone with Asterisk? Is there a better way?
Thanks for any suggestions.
