Abstract
In one embodiment, a device in communication with a service provider network obtains first information regarding a first call leg of a media session associated with a first endpoint. The device also obtains second information regarding a second call leg of the media session associated with a second endpoint. Both of the first and second endpoints are anchored in the service provider network. The device makes a determination that the media session is being hairpinned, based on the first and second information. The device sends, based on the determination, an indication message using Session Traversal Utilities for Network Address Translators (STUN) along the first call leg that causes the first endpoint to begin sending a flow of media packets.
