Requirements
Cisco Unified Cal Manager 11.5 or 12.5ICE Telephony works by configuring a custom SIP Trunk or as third-party SIP advanced endpoints and registering dial numbers(DNs) with a SIP registrar and has been tested to work with Cisco Unified Communications Manager (CUCM) versions 11.5 and 12.5.
These instructions assume the reader is familiar with configuring end users and associated DNs on their CUCM or equivalent registrar. Assignment of dial numbers on the registrar will be required to complete the installation.
Host SystemICE Telephony has been designed to run both inside and outside of the ICE Server's Kubernetes cluster. This deployment model allows network administrators to maintain separate networks for their telephone system and their clustered applications.
The ICE Telephony software acts as a bridge between these systems, picking up SIP/telephony traffic from the network and distributing it to Instant Connect users via a RallyPoint. It should be deployed on a host system on a network with full network access to telephony communications.
