<p>A device for realizing echo counteracting in a switch, the device includes: relay module and echo counteracting unit; the relay module determines the service needed to be echo counteracted based on the call attribute of the service, and sends request information to the echo counteracting unit, requests to counteract the echo of the service; the said echo counteracting unit counteracts the echo for the service needed to be echo counteracted, based on the request information from the relay module. The invention also includes a switch and a method for realizing echo counteracting in the switch. The invention realizes counteracting the echo of the service based on the call attribute, and prevents the waste of echo counteracting resource.</p> |
