Gordon Young
"Why is the keypad so huge? Works well but please add option to make the dialer look like the stock dialer with small keys and not some childish monster sized keypad."
Omar
"Outgoing Call Redirection, Number rewriting, Call integration, MWI and Push service is why I am using app. Feature rich and very well done. Android Auto support would be a nice feature."

森居秀彰
"It's getting better, but there are still plenty of issues. I think a lot of problems can be fixed with configuration but there are a lot of options than make it hard to find them."
Daniel Behrman
"Version 5.5.4 For System Call Integration, incoming calls have no outgoing audio from mic. This is an intermittent issue."
Aubrey
"The best. But I want free. But this doesn't have any problem. So I think pay is good for this. A legjobb. Sajnos nem ingyenes. De megéri fizetni érte. Fél éve használom."
