call - How to know if a user made a phonecall in wp8? -


i prompt user start phone call calling

phonecalltask.show().

that brings him windows yes/no notification screen.

i need know whether user did choose make call or no.

how can know it?

thanks.

there no way know certain. sdk not expose apis tell this.

what instead track amount of time between user leaving app , returning see if call made.

if second or 2 call wasn't made. other conclusion subjective though. if engaged? or went answer phone? count making call?
