An improved B2BUAWM approach for VoIP infrastructure

This article presents a study for VoIP technology to elaborate a differentiated VoIP infrastructure with the proposed approach ProxySIP Bridge. This approach enhances the Back-to-Back User Agent With Media (B2BUAWM) approach in order to isolate the voice traffic from the remaining general purpose traffic and to enable direct voice traffic whenever possible. A differentiated VoIP infrastructure with ProxySIP Bridge is presented, which is an alternative to B2BUAWM original approach.
