The IMG 2020 supports sending UUI (User to User Information) between a called and calling parties. User to User signaling provides a means of communication between two end users through the signaling network for the purpose of exchanging information of end to end significance. The information is transferred transparently through the network and does not have any effect on the call. The IMG 2020 supports UUI for multiple protocols. On the TDM side the supported interworking scenarios are from ISDN to ISDN, ISDN to SS7, and SS7 to SS7. On the IP side the IMG 2020 supports ISDN to SIP. In the ISDN to SIP scenario the IMG 2020 will inter-work the UUI parameters into the SIP INFO message. Information below describes the individual fields within the SIP UUI Support object. UUI Support needs to be configured in SS7 and ISDN to either Pass or Not Pass the User to User information. UUI is configured on a Channel Group by Channel Group basis. For more information such as configuration info, refer to the UUI Support topic
Disable (Default) - Disable is the default setting. When set to disable, the User to User information will not be interworked.

Multi-Level Precedence and Preemption is a priority scheme for assigning precedence levels to calls so the calls are handled in a pre-determined sequence/order and time frame. MLPP can preempt lower priority calls with pre-determined higher level priority calls. MLPP is supported for calls made between the ISDN and SIP protocols as well as between SIP and SIP protocols. For the feature to function, the MLPP field in both the ISDN Channel Group and the SIP Headers object must be enabled. Refer to the Multi-Level Precedence and Preemption - MLPP topic for more in depth information such as call flows.
