IPhone Web App reurn to app after call

I have crea开发者_运维百科ted a web app that produces a list of items to buy, It also gives a link to call the shop using a Tel: link to its phone number.

I want to stay on the app page during the call so the user can read the page out to the shop

Is that possible?

nope, they'd have to open Safari up themselves while on the call.
