Technical scope of Default Dialer App in EU: Access to Cellular Audio Stream for AI Services

Hello,

I am researching the technical feasibility of developing a Default Dialer App for the EU market using the specific entitlements granted under the Digital Markets Act (DMA).

Our primary goal is to implement a Cellular/VoLTE-based calling system—not mVoIP—and we need to clarify whether it is possible to provide features such as STT (Speech-to-Text) and Call Summarization, which require In-call Audio Recording.

Regarding the Default Dialer App Entitlement in the EU, I would like to clarify the following:

Access to Raw Audio Stream: When an app is granted the Default Dialer status in the EU, does it gain programmatic access to the downlink and uplink audio streams of a cellular/VoLTE call for recording purposes?

LiveCommunicationKit & Recording APIs: Does LiveCommunicationKit (or any related framework for iOS 26) provide specific APIs for a third-party dialer to capture native telephony audio?

Entitlement Scope for Partners: If an EU-based partner obtains the necessary entitlements, can those entitlements be used to grant our application the authority to process cellular calls and access the associated audio data?

Recommended Implementation: Are there any Apple-sanctioned methods or specific frameworks for implementing call recording for AI-driven services within the scope of the new EU-specific regulations?

We need to confirm these technical boundaries to establish the implementation scope with our EU partners. Any guidance on whether a third-party app can technically and legally record cellular calls under these specific conditions would be greatly appreciated.

Thank you.

LiveCommunicationKit & Recording: Does LiveCommunicationKit provide any specific APIs or delegates that allow a third-party dialer to capture call audio, or is the recording still restricted by the system’s sandbox?

Entitlement Scope: If our EU partner obtains the necessary entitlements, can they authorize our application to handle the cellular call processing entirely, including the access to telephony audio data?

AI Service Implementation: Are there any Apple-recommended ways to implement AI features (STT, Summarization) within a Default Dialer App without violating current iOS security architectures?

We need to provide a clear "Feasibility Report" to our EU partners during upcoming meetings. Any technical guidance on whether a third-party app can legally and technically record cellular calls under this new EU-specific policy would be extremely helpful.

Thank you.
