Abstract
A system for communicating with an Internet Protocol Multimedia Subsystem (IMS) network is provided. A system that incorporates teachings of the present disclosure may include, for example, an intermediate node having a controller element to receive from a non IP Multimedia Subsystem (IMS) compliant node a Session Initiation Protocol (SIP) message having a calling party number and a called party number, and insert in the SIP message a request that instructs a receiving IMS-compliant node to bypass validation of the calling party number. Additional embodiments are disclosed.
Claims23
A computer-readable storage medium, comprising computer instructions for:
- receiving a Session Initiation Protocol (SIP) message having a calling party number and a called party number, wherein the SIP message corresponds to a request to establish communications with a communication device by way of an IP Multimedia Subsystem (IMS) network according to the called party number;
- inserting in the SIP message a request to bypass validation of the calling party number;
- and
- forwarding the updated SIP message to a network element of the IMS network to establish communications with the communication device.
An intermediate node, comprising a controller element to:
- receive from a non IP Multimedia Subsystem (non-IMS) compliant node a Session Initiation Protocol (SIP) message having a calling party number and a called party number;
- and
- insert in the SIP message a request that instructs a receiving IMS-compliant node to bypass validation of the calling party number.
An IP Multimedia Subsystem (IMS)-compliant node, comprising a controller element to:
- receive a Session Initiation Protocol (SIP) INVITE message;
- and
- forego a process to validate a calling party number in the SIP INVITE message.
A non-IP Multimedia Subsystem (IMS) compliant node, comprising a controller element to transmit a Session Initiation Protocol (SIP) message to a session border controller that inserts a request in the SIP message to bypass at least one among a validation and originating treatment of the calling party number.
