Voice Source-Group This feature was added in 15.1(2)T but is not implemented in many modern deployments. Other Security methods for Cisco IOS/CUBE are usually deployed. The CUBE Application Security overview can be seen in this whitepaper starting at section 4.2. Cisco Unified Border Element (CUBE) Management and Manageability Specification Command Syntax: Voice Source-Group Feature Dial-Peer Permissions This configuration allows an administrator to restrict a dial-peer to either allow inbound connections only (term / terminate) or egress connections (orig / originate). This would be like explicitly configuring an inbound dial-peer to only be used for inbound calls and an outbound dial-peer for outbound calls. The default for any dial-peer is to allow both inbound and outbound connections. This CLI is not often deployed in modern deployments.

URI and Digit Manipulation At some point in a collaboration deployment an administrator can need to manipulate digits or a URI / SIP Header. Cisco Gateways have numerous methods for digit manipulation which allows an administrator complete control over how and when a digit can be manipulated. However, this is not always easy and some people become overwhelmed with the different options or the administrator does not know an option exists.
