    // 1. In admin portal, configure a test extension to use only G.711 alaw. Make a call and capture SDP.

    // 2. Repeat with G.729: verify annexb, SDP shows g729/8000.

    // 4. Repeat with G.722: verify SDP shows G722/8000.
    // 5. Test codec fallback: configure preferred codec that remote doesn't support; verify negotiation falls back to next common codec.
