public class BackToBackCall

BackToBackCall is a back-to-back user agent (B2BUA), which divides the communication session between two call legs and mediates all SIP signaling from call establishment to termination between both ends of the call. Common B2BUA usage is for agent anonymization in ACD (automatic call distribution) and support for other mid-way call control features.
