Programmable Voice Issue with iOS 16.4 #527

Closed dbarkman closed 6 months ago

dbarkman commented 1 year ago

Description

Note: This issue is not reproducible on iOS 16.3 and earlier, only 16.4. When testing Call Waiting with Programmable Voice, on an iPhone running the new, iOS 16.4, once both calls are on, one on hold the other active, then I try swapping the calls, placing the active on hold and resuming the held call, the Xcode debug view shows many AVAudioSession errors and both calls get disconnected.

Steps to Reproduce

  1. Take an incoming call to the app running the Twilio iOS SDK
  2. Take a second incoming call, puts first call on hold
  3. Swap calls to resume first call and put second call on hold

Code

// no code to show for this error

Expected Behavior

Calls should be able to be switched many times, no known limit to how many times we normally can swap calls.

Actual Behavior

Both calls are hung up.

Reproduces How Often

Every time

@bobiechen-twilio would you be able to review this issue?

Hello, To enable support for multiple voice calls at the same time, the maximumCallGroups property needs to be set to a value of 2 or greater when you configure the CXProviderConfiguration for CallKit. After setting this property, the CallKit screen will allow switching between the ongoing calls. The user will only need to update their VoIP app's UI to show the correct information about the current active call. We have opened a PR with the necessary changes to support multiple calls in the Voice iOS Quickstart app: https://github.com/twilio/voice-quickstart-ios/pull/557
