Purpose

Production-grade voice + video calling for native Android v5. Loaded by the cometchat-calls dispatcher when the project is Android v5 (detected from chat-sdk-android:4.x / chatuikit-android:5.x or asked when greenfield). Operates in two modes:

Standalone — calls is the product. No chatuikit-android UI Kit; just chat-sdk-android (for signaling) + calls-sdk-android + your own UI surfaces (CallButton on profile, CallLogsActivity, OngoingCallActivity).
Additive — calls layered onto an existing v5 chat integration. The kit's CometChatMessageHeader already exposes call buttons; this skill wires them to the Calls SDK and mounts the global IncomingCall listener at app root.

Read these other skills first:

cometchat-calls — the dispatcher (mode selection, hard rules, anti-patterns)
cometchat-android-v5-core — Chat SDK init, login order, local.properties + BuildConfig credential conventions, Application class wiring
