Two-party connections between IP endpoints are not subject to the administrable loss plan of the switch. Due to this exemption, audio levels do not change when a two-party call changes from the TDM bus to a shuffled or hairpinned connection. Although IP endpoints can be assigned to administrable loss groups, the switch is only able to change loss on IP Softphone calls including circuit-switched endpoints. Conference calls with three parties or more are subject to the administrable loss plan, regardless of whether the calls involve IP endpoints or not.
