The gateway cut, without pretending to be the CUBE guide · Ecosystem
Glossary. IVR module: A named block in the IVR Administrator's Guide, such as Menu, Play, If/Else, or Skill Transfer. IVR modules
Sister technologies. Zoom Phone and Microsoft Teams. Named prebuilt connections. A local UC client is also about 320 kbps. APIs and SDKs
Config. Two columns: what the Five9 PDF says, and what you still must confirm on the gateway.
Troubleshooting. The gateway is sending a private plan the DNIS table does not contain. Fix the called number, with the gateway guide open.
Cross-platform bridge. A mapping to another PBX or contact center is a teaching bridge. It is not an import button.
Future hook. The guide's cloud endpoint stays unset. Confirm before relying on a dated catalog or a case-study number.
