Abstract: Internet protocol (IP) based calls from a first terminal in an IP based communications system are routed to a second terminal in another communications system. In response to a call setup request at a common communications core that is common to both the IP based communications system and the other communications system, a query is transmitted to a private telephone number mapping database that contains routing information for terminals in both the IP based communications system and the other communications system requesting routing information for the second terminal. Routing information for the call setup request is received from the private telephone number mapping database for routing the call.

Abstract: Efficient telephone number mapping (ENUM) based call routing during area code splits is described. An ENUM domain management component can associate an ENUM domain name with multiple records when a numbering plan area code split links an old area code of a telephone number corresponding to the ENUM domain name with a new area code. An ENUM provisioning component can perform permissive dialing of the old and new area code during ENUM based call routing by utilizing the multiple records.

Abstract translation: 描述了区域代码分割期间基于呼叫路由的高效电话号码映射（ENUM）。 当编号方案区域代码拆分时，ENUM域管理组件可以将ENUM域名与多个记录相关联，将与ENUM域名对应的电话号码的旧区域代码与新的区号相链接。 ENUM配置组件可以通过利用多个记录在基于ENUM的呼叫路由期间执行旧区和新区域代码的允许拨号。

Abstract: Aspects of the subject disclosure may include, for example, providing a request associated with a call session to a server, wherein the request includes capability information associated with user equipment. A codec is identified according to the capability information to obtain an identified codec, which facilitates media service to the user equipment. The media service is accessed from a media resource function, which in turn, is accessed by the server responsive to the identified codec. An operable resource identifier is identified responsive to a search of a codec table, wherein the server accesses the operable resource identifier associated with the media resource function from a domain name server responsive to the resource identifier not being available at the codec table. Other embodiments are disclosed.

Abstract: A content delivery network includes an overlay network having a plurality of cache servers. Each cache server configured to receive a request from a personal content server to register with the content delivery network, receive a request from a mobile capture device to establish communication with the personal content server, and establish a communication path through the overlay network between the mobile capture device and the personal content server. Each cache server is further configured to transfer content from the mobile capture device along the communication path to the personal content server.
