Hello!
I develop a voicemail app service and I use MMI codes to let users enable/disable call forwarding to their voicemail number.
For example, the app opens the Phone app with a code such as:
**21*<phone number>#
This is expected behavior and is required for the service to work.
However on iOS 27, those links are now blocked with a “Malicious link blocked” warning, saying that the link may forward incoming calls/messages.
Is there any supported way for apps with a legitimate use case like this to request an exemption, or otherwise avoid this warning?
