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.
