Avaya, UCCE, and the pages that did not open

A migration story that says we left UCCE needs a source for what UCCE is. That source is not in this session. Use the UC lab for the Cisco-shaped course, and mark any step you have not opened. Do not borrow a dial-peer command from memory.

  • The UC Lab Free University opened on this organization's site. Its own pages study CUCM-shaped systems.
  • This CPaaS session did not open Cisco CUCM or UCCE documentation. Those menus stay confirm.
  • Avaya product pages were not opened in this session either. Aura and Infinity stay confirm here.
  • Bandwidth's integration list does name Zoom Phone, Webex Calling, Genesys Cloud CX, and Five9. Those names opened.
  • The Zoom, Talkdesk, and Avaya sibling lab URL returned HTTP 404 in October 2026, so it is not linked.

What is going on

A migration story that says we left UCCE needs a source for what UCCE is. That source is not in this session. Use the UC lab for the Cisco-shaped course, and mark any step you have not opened. Do not borrow a dial-peer command from memory.

Avaya is a common source PBX in the brief for this lab. Without an Avaya page opened here, the only honest line is confirm. The sister labs that did open are listed on the ecosystem page with their titles.

Worked example

Write the source system in one column and the citation in the next. Bandwidth to Zoom Phone: the Bandwidth home page. CUCM translation pattern: confirm, or a link you open yourself. Avaya trunk group: confirm.

Quiz

1. This session opened the UC Lab Free University site.

2. The Zoom, Talkdesk, and Avaya lab URL is linked because it opened.

Ecosystem

Sister pieces sit on the ecosystem page: the glossary, the mind map, the integration map, and the bridges.

  • Confirm — The mark for a CUCM, UCCE, or Avaya step that this session did not open.
  • UC lab — The sibling course that did open, for the Cisco-shaped material.

Config. Do not paste a CUCM XML dump into this lab. It was not a source, and it may contain numbers you should not publish.

Troubleshooting. If a design review demands an Avaya vector step, the answer from this room is confirm, then open Avaya's documentation.

Bridge. SIP between a legacy PBX and a CPaaS is still the trunk article: private domain, public domain, trunk.

Mind map, sister technologies, and future hooks live on the ecosystem page.
