A system allows a user to send alias information or receive alias information during a communication between two communication devices. Alias information is identity information for a user that identifies the user on a social media site or network (e.g., Facebook, Twitter, LinkedIn, etc.). The alias information can be stored in a contacts program or other data store. During a web-based telephone call between two IP-enabled phones, the alias information may be retrieved. The alias information can then be sent to the other IP-enabled phone or to another device associated with the calling party. In response to receiving the alias information, the calling party can automatically retrieve information associated with the called party and the alias from one or more social media sites.
