Abstract: Embodiments of this application relate to a call system, an extension, and a host in the field of communication technologies. An example call system includes a host and an extension. A network side device and the host are connected through a network side link, and the host and the extension are connected through a first terminal side link. The extension exchanges a call data packet with the network side device through the first terminal side link and the network side link. The extension and the host transmit the call data packet through a second terminal side link in response to determining that call quality of the extension is lower than a quality threshold. The first terminal side link is different from the second terminal side link.
