The host device and the peripherals can synchronize wall clocks. The system sets up a call (or receive a call) from a remote host device, and requests the peripherals to check for network connectivity to the remote host device (connectivity check). This check can be done by using a STUN/TURN procedure. The system establishes direct connectivity between the peripherals and the remote host device and monitors lip sync by transferring RTCP messages between the host device and the peripherals and instructing display and playback peripherals/sub systems to align lip sync. ## Claims ### Claim 1 A method comprising: detecting, at a host device, a first peripheral and a second peripheral, wherein the host device is a first user communication device;
