SIGCOMP compresses the payload of the SIP packets. ROHC compresses the IPv4, IPv6, UDP, UDP-Lite, RTP, TCP headers. There are 2 different ways to reduce bandwidth usage. There are not incompatible: you can use SIGCOMP to compress the payloads of the IP/UDP/SIP packets and ROHC for the headers of the IP/UDP/SIP and IP/UDP/RTP packets. The ROHC compression of the IP/UDP/SIP packets will not be very interesting because headers are small in comparison to payloads (unless SIGCOMP is very efficient on the payload).
