Question #195843 on rohc changed:
https://answers.launchpad.net/rohc/+question/195843

Cedric Baudoin proposed the following answer:
SigComp will only compress the SIP signaling (data part not the header
part) between for example the client and the SIP proxy, whereas ROHC will
compress the RTP flows (only the header part) based on the classifier
configuration

Best regards
Cédric
