After this course you will configure advanced Cisco voice features on your own: you will analyse SIP call flows, build globalised call routing across several sites and clusters, run Cisco Unified Border Element as the hand-off to your provider and protect branches with SRST. Mobility features such as Extension Mobility and Unified Mobility are covered too, along with Call Admission Control. The course is aimed at collaboration engineers and administrators who already run Cisco Unified CM and are preparing for the 300-815 CLACC exam for CCNP Collaboration.
What you’ll take away.
- Analyse SIP sessions and media protocols and isolate faults in the call flow
- Implement globalised call routing in Cisco Unified CM, including between clusters with URI dialling and ILS
- Configure Cisco Unified Border Element and troubleshoot SIP trunks
- Set up Cisco Unified CM Express and SRST for branch sites
- Configure Extension Mobility, Unified Mobility, Call Admission Control and AAR
Your training in detail
- Who is it for?
- Collaboration engineers and administrators who run and extend Cisco voice in their organisation and are aiming for the 300-815 CLACC concentration exam for CCNP Collaboration.
- Prerequisites
- You know networking, voice and video basics such as codecs, QoS and SIP call setup, work with the Cisco IOS XE command line and have already configured Cisco Unified CM users, device pools and dial plans. Knowledge of gateways, PSTN access and media resources is assumed.
- Format & planning
- Standard length: 5 training days. A different length can be arranged for companies.
Agenda: from understanding to application
Our independently developed agenda proposal. Focus areas, lab environment and scope are agreed before booking.
SIP and media: call flows, early media, hold, transfer and conferencing
Cisco Unified Border Element: dial peers, DTMF, codecs, SIP profiles and security
Cisco Unified CM Express and enhanced SRST for site failover
Globalised call routing, time-of-day routing, URI dialling and ILS
Call Admission Control, AAR and troubleshooting multisite deployments
Supplementary services: call park, call pickup, Meet-Me, call coverage and recording
Extension Mobility, Unified Mobility, and ILS with Global Dial Plan Replication between clusters
In the lab you connect two sites: you set up globalised routing with partitions and calling search spaces, bring up a SIP trunk to the provider through CUBE and simulate a branch WAN outage so that SRST takes over. You then analyse a deliberately broken SIP call flow from the debug output.
Exams, licences & credentials
The course prepares you for the 300-815 CLACC exam (Implementing Cisco Advanced Call Control On-Premises). Passing it earns the Cisco Certified Specialist – Collaboration Call Control & Mobility Implementation certification from Cisco; together with the 350-801 CLCOR core exam it meets the requirements for CCNP Collaboration. The exam and its fee are included only if the offer explicitly confirms this. This is not an official Cisco course unless the offer states otherwise.

Frequently asked questions
Why is the exam called CLACC and the course CLACCM?
Cisco now lists exam 300-815 as Implementing Cisco Advanced Call Control On-Premises (CLACC). The course keeps the CLACCM name and is listed by Cisco as preparation for this exam. The current exam topics also include remote access and B2B connectivity through Expressway, so plan extra study time for those.
Do I need to have taken CLCOR first?
Not formally. Cisco does recommend knowledge at the level of CLFNDU and CLCOR, because the course starts straight away with advanced configuration in Cisco Unified CM.
Does Implementing Cisco Advanced Call Control and Mobility Services (CLACCM): call control and mobility with Cisco UCM include a certificate?
The course prepares you for the 300-815 CLACC exam (Implementing Cisco Advanced Call Control On-Premises). Passing it earns the Cisco Certified Specialist – Collaboration Call Control & Mobility Implementation certification from Cisco; together with the 350-801 CLCOR core exam it meets the requirements for CCNP Collaboration.
