dialtone-handshake skillA

dialtone-handshake is agent-read markdown (skill) from calle-ai/awesome-phone-call-agents: Use when an AI phone call agent (outbound caller or inbound voicebot) needs to recognise that the other end of the call is also an AI, switch to a compressed machine mode, and label call results by who actually attested them (human, phone system, or AI agent)..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add calle-ai/awesome-phone-call-agents/dialtone-handshake@git:20260914.cb33c28
Exact content
mdr add calle-ai/awesome-phone-call-agents/dialtone-handshake@sha256:4b02a3376db442cb

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
