And you can get another google voice number by adding another email, and transfer the landline number to that account.
I used to think the landline number was important (ported to tracphone), but it really fell by the wayside and I let it go...
I have used Google voice for 10 years or so. My previous landline number and my previous cell phone number are ported to it as well as another google voice number I originally had. It also serves as my voicemail for my cell phone. Porting was a one time $20 charge per number. Otherwise it is free. If you want to make international calls you have to deposit money in your google account but that is easy. International calls are then generally a few cents a minute. I think I deposited $20 a decade ago and have not run out but I rarely make international calls.
I have my cell phone set up so that if I dial an international number it routes the call through google voice rather than Verizon so that saves me money as well.
If you want a classic looking "landline" phone in your home I am sure there are solutions for this. Personall I think landlines are on their way out.
