A bit of a background. Thinking of moving away from a softphone, which I predominantly use for a long distance calls, a few months ago I got myself a Linksys SPA3000, got it configured (was not easy, but ...) only to find that I wasn't really using it (kept using internet softphone application to long distance calls as it was easier).
But when I got a mobile phone with a SIP client - I almost immediately stopped using softphone in favor for SIP calls on mobile.
Since running Linksys SPA3000 all the time is not going to get our Earth any greener, I am wondering thinking of getting rid of it. But at the same time (since I am not very knowledgeable in a phone technologies) - I would like to ask - what I am missing (features, etc) by not using VoIP on a landline?
Just to get things straight (because I know I could be misusing the terminology): when I say "VoIP" I mean - making cheap long distance calls using the landline phone connected to VoIP router (connected to the internet router with a cable), and when I say "SIP" I mean making cheap long distance calls using the SIP client on a mobile phone (connected to the internet wirelessly).
