Currently you can specify which calls you would like to delete in the call log on Service Web but not on the mobile app.
Absolutely not! We actually had a former employee 'loan' out her RC sign on to a relative and use her RC mobile app for personal use while on vacation in Mexico. We would never have known this if she had had the ability to delete her own calls. She was a trusted employee, but you never know.
Can we have an option to delete a missed call in the mobile phone app one at a time? Currently only option we have is to delete all. Unlike with the desktop phone app we can delete a call log entry one at a time.
