Hi@sec4zj,
Based on the issue that you mentioned, do you want to capture the phone number of the person who is on call for the current week?
Could you please share more about your scenario, more details about the SP list columns?
@cds provides a direction where assumes that you have an SP list where you have a PhoneNumber column and a Date column. What I want to confirm is, if there is a PhoneNumber column or just a Person column.
If it is a PhoneNumber column, you can try the formula @cds provided. What's more, I advise you to add a Gallery to display the record. The LookUp() will filter the PhoneNumber you want. Besides the PhoneNumber, you can add a button and set the OnSelect property as below to call the person on call this week.
Launch("tel:"&Field)
If it is a Person column, you should first get the corresponding phone number to the person through the Office365 connector. In general, we use the following formula to get the phone number.
Office365Users.UserProfile(InfoAbout.Text).mobilePhone
Best Regards,
Qi
