CLCEI Training for Your Team — Implementing Cisco Collaboration Cloud and Edge Solutions
The moment a collaboration platform has to work from a home office, a hotel, or a partner company, it stops being a LAN application and becomes an internet-facing service — with certificates, traversal, federation and a firewall team to negotiate with. CLCEI (Implementing Cisco Collaboration Cloud and Edge Solutions) is the course for exactly that boundary: the Expressway edge, mobile and remote access without VPN, business-to-business calling, and the hybrid services that tie on-premises call control to the Webex cloud.
It prepares for exam 300-820 CLCEI, a CCNP Collaboration concentration that pairs with the 350-801 core to complete the certification. Teams typically book it ahead of a remote-access rollout, a B2B federation project, or a hybrid cloud migration — the projects where an expired certificate can take down calling for everyone outside the building.
As a training operator, we arrange delivery through authorized partners with vetted instructors who run collaboration edges in production — live online in your time zone, on site, or as a private group shaped around your architecture.
Who this course is for
- UC engineers extending an on-premises platform to remote and mobile users
- Teams running or planning Expressway pairs and hybrid Webex services
- CCNP Collaboration candidates choosing the cloud and edge concentration
- Security-adjacent engineers who own the collaboration edge and its certificates
What your team will learn
Topic areas below are grouped in our own words. The full official agenda is available on request — it comes from the authorized partner as part of your quote.
- Edge architecture with Expressway: letting collaboration traffic in without letting everything in
- Mobile and remote access — soft clients and endpoints working from anywhere, no VPN required
- Business-to-business calling with other organizations, federated and secured
- Hybrid services connecting on-premises call control to the Webex cloud
- Certificates, traversal and firewall rules: where edge deployments actually fail
- A troubleshooting method for problems that only happen from outside the office

CLCEI vs alternatives: which to choose
Factual criteria only — level, duration, audience and certification. The right choice depends on your team's starting point and stack.
Cisco CLCOR (Collaboration Core)
The prerequisite core course for exam 350-801: call control, dial plans and endpoints inside the perimeter. Take CLCOR first — CLCEI assumes that platform exists and teaches how to expose it safely to the internet and the cloud.
Cisco CLCNF (Collaboration Conferencing)
The conferencing-focused advanced course: meeting platforms, scheduling and scale. Choose CLCNF when the project is meetings infrastructure; CLCEI when it is remote access, B2B calling and hybrid cloud connectivity. Many edge projects eventually need both.
A custom intensive
Rolling out mobile and remote access as a single project? A custom 2–3 day program on our materials can cover exactly the Expressway, certificate and firewall scope of your rollout — without the full concentration curriculum.
Need only part of CLCEI?
If your team needs a subset of this program — or a mix of topics from several courses — we build a custom 2–4 day intensive on our own materials, shaped by your infrastructure. One custom program typically replaces 2–3 catalog courses.

Where does CLCEI fit in the CCNP Collaboration path?
CLCEI is a concentration course preparing for exam 300-820. Together with the core exam 350-801 (covered by CLCOR) it completes CCNP Collaboration. It is the concentration to choose when your projects involve remote access, B2B calling or hybrid cloud services.
Is this course still relevant if we are moving to Webex cloud calling?
Usually yes. Most enterprises run hybrid for years — on-premises call control plus cloud meetings and messaging — and CLCEI covers precisely that connective tissue: hybrid services, edge traversal and the certificate infrastructure both sides depend on.
Why do edge deployments have a reputation for being painful?
Because they combine three failure domains: certificates, firewall traversal and DNS. Each is owned by a different team in most organizations. The course teaches the full chain end to end, so your engineers can diagnose problems instead of forwarding them.
How hands-on is the course?
Labs cover configuring the collaboration edge, enabling mobile and remote access, securing business-to-business communication and validating certificate chains. In a private group, the instructor can mirror your intended architecture and rehearse your specific rollout sequence.
