Hello,
We’re working on a connected watch that displays notifications and handles calls using the ANCS (Apple Notification Center Service) on a Nordic Semiconductor platform. We can manage a single call by monitoring notifications with Category ID: Incoming Call and Category ID 12: Active Call, which lets us display the call status on the watch. However, we’re facing challenges with handling multiple calls, especially around holding and resuming calls.
Our key issues are:
-
Tracking Call on Hold: When the first call is put on hold to answer a second call, ANCS removes the first call notification. This leaves us unable to track if there’s a call on hold until it’s resumed and reappears as an Active Call. Is there any ANCS flag, category ID, or other mechanism to indicate a call is on hold?
-
Tracking Total Call Duration: When resuming a held call, ANCS assigns a new Active Call category ID with a new timestamp, which reflects the resumption time rather than the original call start time. This complicates tracking the total elapsed time. Is there a way to identify that this resumed call is the same as the original one to retain the initial timestamp?
Any insights or workarounds would be greatly appreciated!
Thank you.
