Genesys Cloud Communicate for iOS is a native mobile application offering comprehensive call management, conferencing, voicemail, and presence capabilities integrated with the Genesys Cloud ecosystem. The application requires WebRTC phone setup as the default device and supports outbound calling using organization phone numbers, conference management with participant controls (hold, confine, removal), and voicemail management through the Inbox with collaborative note-taking. Call history tracking includes queue information, duration, and wrap-up codes, while callback functionality and External Contacts search (limited to five results) are available. Contact center features encompass transferred ACD calls, directly routed ACD calls, and on-queue ACD calls, with After Call Work requiring wrap-up code selection and optional notes. Call notifications alert users to incoming calls, missed calls, and voicemails, though group mailbox voicemails do not generate notifications. Presence management allows users to set and persist status across clients via the Remember Status feature with customizable ringtones. Call timeout on mobile devices is set at 30 seconds, with potential continued ringing on other applications if administrators configure longer values. Technical requirements include granular permissions for conversation management, mobile access, push notifications, voicemail, presence tracking, and ACD functions. Authentication sessions expire after 30 days for standard organizations and 15 minutes for HIPAA-compliant organizations, with expiration periods not customizable. The platform maintains FedRAMP compliance and supports Mobile Device Management browser authentication through Chrome, Edge, and WorkspaceOne. Key limitations include no support for group voicemail notifications, presence customization, third-party app calling, or integration with Genesys embedded clients such as Genesys Cloud for Salesforce, and deleted group voicemails cannot be restored.
