I saw www.calltrackingmetrics.com ; ringcentral.com ; twilio.com ; Zadarma. At this moment it seems that calltrackingmetrics seems to be the first solution I would try because they put in front of their ads the fact to track with google ads. Twilio seems to be too much complex to use and they don't have an iPhone app ; ringcentral I don't know and Zadarma seems good. Source: about 5 years ago
I use unitelvoice.com. It works fine has an app and can forward to my cell number. Used to use ringcentral.com it was fine when it worked but support was crap. Source: over 5 years ago
