Integrated Calling with AT&T Office@Hand
Article #9205

How do I answer a call to the Office@Hand app on my iOS device even if my phone is locked? How do I manage a call to my mobile number while I am on a call with the Office@Hand app?

The Office@Hand Mobile app includes a capability provided by Apple – CallKit, which gives the Office@Hand app more control of the mobile device when in a call, and allows the user to answer calls more easily when the device is locked. CallKit allows an ongoing Office@Hand call to remain active even if a second call comes to your mobile number while using the Office@Hand app.

The Office@Hand Integrated Calling feature makes it possible for an iOS device user to manage multiple calls without unlocking the screen, and without losing an ongoing call or an incoming call. A user can simply manage the feature by either enabling or disabling the Integrated Calling feature on your Office@Hand Mobile app settings.


When Users are on a Office@Hand call and a mobile call comes in, the iOS system overtakes the call and pushes the non-iOS apps or calls into the background, putting the Office@Hand call on hold. The call goes automatically on-hold or forces the user to fumble around trying to open the call from the push notification or navigate to another screen to interact with the incoming call in real-time.


With the latest version of Office@Hand for Mobile, iOS device Users are provided with a better call experience – an incoming screen appears, allowing them to interact with the call with 1-touch, either from a locked screen or when engaged in an active Office@Hand call.

Call Log visibility

When Integrated Calling is enabled then Office@Hand calls will be listed in the iOS device’s native call log. Missed calls are displayed in red, and Users can return a missed call by tapping a number on the call log. Office@Hand calls are labeled as “Office@Hand Audio” underneath the caller ID. The Users also have a set of standard features available to call or text a contact that is in the call log.
Note: You may disable Integrated Calling, however, this setting would cause your Office@Hand calls to be interrupted by incoming mobile calls.

Differentiating an Office@Hand call from a personal call

Office@Hand calls are displayed as “Office@Hand Audio” in the incoming call screen and in the native call log, whereas a personal call would only display a contact’s name or just a number. The table below displays this difference.
