    Abstract: Examples disclosed herein provide methods and systems for selecting Internet Protocol addresses for Session Initiation Protocol (SIP) communications. In at least one implementation, a method of operating a communication network utilizing a session initiation protocol (SIP) is provided. The method performed within a second communication device includes receiving a SIP invite from a first communication device, and determining a source IP address for the second communication device, using an IP address for a third communication device as a destination address within a source address selection algorithm (SASA) function. The method further includes adding a Via header within the SIP invite to include the SASA determined source IP address for the second communication device, adding a Record-Route header within the SIP invite to include the SASA determined source IP address for the second communication device, and transferring the modified SIP invite to the third communication device.

    Abstract: A method, system, device, or apparatus for selecting an IP address for a message. The method, system, device, or apparatus is used when there are two or more IP addresses for a multihomed device. The method determines an IP address reachable from a destination for the message. The message is generated using the reachable IP address as the hostname of the multihomed device. The generated message is transferred to the destination.

    Abstract: Embodiments disclosed herein provide systems, methods, and computer readable media for extending the lifetime of a network address when an address system is unavailable. In a particular embodiment, a method provides, upon determining that a first network address for a network element has reached a preferred lifetime for the first network address, transitioning the network element to an extended rebind state that allows the first network address to remain in the preferred state. While the network element is in the extended rebind state, the method provides attempting to contact an address system and determining whether a second network element is assigned the first network address. The method further provides maintaining the first network address in the preferred state and the network element in the extended rebind state until contact is made with the address system or the second network element is determined to be assigned the first network address.

    Abstract: Examples disclosed herein provide methods and systems for selecting Internet Protocol addresses for Session Initiation Protocol (SIP) communications. In at least one implementation, a method of operating a first communication device includes applying a source address selection algorithm to determine at least one source Internet Protocol (IP) address for the first communication device, and transferring a communication invite that indicates the at least one source IP address. The method further provides, receiving, from a second communication device, a response to the invite that indicates at least one IP address for the second communication device, applying SASA to the at least one IP address to determine a third source IP address for the first communication device, and initiating a communication with the second communication device using the third source IP address.
