Introduction:
From the website.
OpenSER is a project spawned from FhG FOKUS SIP Express Router (SER). The reason for this new venture is the lack of progressing and contributions to the SER project from the other SER team members as well as the reticence to new contributions from project’s community members. We want to accelerate the integration of public contributions to the SER project.
