libSigComp API

libSigComp project is a complete and compliant SigComp API to speed-up SigComp integration in Open-Source IMS projects. libSigComp is released under LGPLv3 license.

As many operators have begun to commercially deploy IMS, the relevance of using SigComp to lower bandwidth usage will come quickly. In my own opinion I think that most operators (especially those using RCS) will question how to reduce SIP signaling (registration, billing, presence, messaging …) bandwidth usage (who will pay bits?).
These questions will especially concern using SIP (or all other text-based protocols) in wireless handsets as part of 2.5G and 3G cellular networks.
