Cisco Unified Communications Manager

This section is still under development as of March 2019.

Cisco Unified Communications Manager is Cisco’s communications offering. It was previously known as Cisco CallManager.

Over the years I’ve used various versions of both Communications Manager and Communications Manager Express. As of writing the system that controls my communications at home is CME 12 running on a Cisco 2921 ISR G2 router.

This section contains hints and tips that I’ve picked up over the years. It’s a work in progress.

Cisco CallManager 3 with Asterisk VM — Using Asterisk to provide voicemail to Cisco CallManager over H323.
Cisco CallManager 4 with Asterisk VM (SIP) — Using Asterisk to provide voicemail to Cisco CallManager over SIP.

Conditions of use: Whilst I will aim to have all instructions and information as accurate as possible, you are responsible for any changes you make to your system.
