I was in a similar position lately until I found Okular. Have you tried it? https://okular.kde.org/. - Source: Hacker News / 10 months ago
I would try Okular first, though, which is free and open source: https://okular.kde.org/. Source: about 1 year ago
KDE's okular might be a good choice. I haven't personally used it for epub but I know it supports it. https://okular.kde.org/. - Source: Hacker News / about 1 year ago
I use okular, don't think it has web export though. Source: about 1 year ago
Systems like 8x8/RingCentral/Vonage or even Voip.ms might be ideal for you. Source: over 2 years ago
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 3 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 3 years ago
