The compression plugin infrastructure (-c option) was added in 2003 but no sippcomp.so plugin was ever distributed with SIPp. This was likely intended for SigComp (RFC 3320, updated by RFC 4896) support that never materialized. If SigComp support is desired in the future, it should be implemented properly as a built-in feature rather than through an undocumented plugin interface.
