Foundations and the domain ยท foundation ยท 12 min full read

You sign into one domain. Skill groups, users, lists, prompts, scripts, and campaigns live there. Another domain does not inherit them.

Five9 does not use CUCM-style partitions and calling search spaces. If you are coming from Unified Communications Manager, do not look for a partition table. Look for the domain, then skills and campaigns. That mapping is a teaching bridge, not a vendor migration wizard.

Objects that do not leak into the next domain.

Worked example

Draw the boundary

Sketch two domains and refuse to share a list between them.

  1. Name three objects that stay inside a domain
  2. Write the CUCM idea you will not look for
  3. Say which roles can join a skill

A teammate can repeat the boundary without saying 'partition'.

Can campaign A in domain East use a list from domain West?
What replaces a CUCM partition in this lab's map?
Who can sit in a skill group?
A user can be in how many skill groups?
A campaign can have how many skill groups?

Ecosystem

Glossary. Skill group: Agents or supervisors who can take a campaign's work. A user and a campaign can have more than one. Skill groups

Sister technologies. Salesforce IVR module. A script module, including SFDC Einstein. Different from the desktop adapter. IVR modules

Config. Sketch two domains and refuse to share a list between them.

Troubleshooting. The agent is logged in and Ready, and the queue never offers the call. Add the user to the Billing skill group.

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.
