I'd be more than happy to assist you. I think you might want to have a look at Google Voice. If works from a landline, a computer, or an Android cell phone. Lots of options, and it's free. Click below for more information.
If that's not what you're looking for let me know, but based on your aforementioned requirements, I think Google Voice will suit your needs.
You do not have an idea of my question. Do you know what PVA are? Phone numbers that works on craiglist for verification? They cannot be VOIP numbers like google voice. They must appear like landline number when searched.
Which phone company offer this service please?
