    摘要: A method of processing a Voice over Internet Protocol (VoIP) call is disclosed. The method includes receiving a Uniform Resource Identifier (URI) associated with a destination telephone number from a telephone number mapping (ENUM) server associated with a third service provider. The method also includes receiving an Internet Protocol (IP) address of a Session Initiation Protocol (SIP) server associated with a second service provider in response to a query by a first service provider to a Domain Name Service (DNS) server. The query is based on the URI. Additionally, the method includes contacting the SIP server using the IP address of the SIP server to set up a bearer path of the VoIP call.

    摘要: A Voice over Internet Protocol (VoIP) call from a first provider to a destination telephone number served by a second provider comprises sending a Session Initiation Protocol (SIP) INVITE message from an originating switch to a first SIP server of the first provider. The first SIP server queries a telephone number mapping (ENUM) server of either the first, second or a third provider, and receives a Uniform Resource Identifier (URI) associated with the destination telephone number. The ENUM server may be internal or external to the first provider. The first provider queries a Domain Name Service (DNS) server based on the URI, and receives an Internet Protocol (IP) address of a second SIP server of the second provider. The first SIP server and the second SIP server are used to set up a bearer path for the VoIP call between the originating switch and a destination switch.
