Signaling Compression (SigComp) is a solution for compressing messages generated by application protocols such as the Session Initiation Protocol (SIP) and the Real Time Streaming Protocol (RTSP). The decompression functionality is provided by a Universal Decompressor Virtual Machine (UDVM) which provides an instruction set optimised for decompression algorithms. The bytecode for decompressing the compressed message is transmitted with the message.

Feedback mechanism
RFC3320
Suite doesn't include feedback request in SigComp messages and doesn't handle request if it receives one in SigComp message.
