Summary
iOS Talk set to Gateway Default appears to ignore the Gateway speech/TTS configuration for Microsoft Sonia and instead resolves to Realtime Voice / Native WebRTC, producing the non-Sonia realtime voice.

}iOS Talk Status
The iOS app status screen shows:
Provider: Gateway Default
Voice Mode: Realtime Voice
Transport: Native WebRTC
Expected Behavior
iOS Talk using Gateway Default should honor the Gateway talk.provider: "microsoft" and speak with en-GB-SoniaNeural.
Actual Behavior
iOS Talk still resolves to Realtime Voice / Native WebRTC and uses the same non-Sonia voice.
Question
Is this a bug, a missing feature in iOS Talk's Gateway Default handling, or the current intended limitation of the app?
