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.
