Abstract
A system is configured to receive, from a user device, voice traffic to be sent to another user device; determine whether the voice traffic is local traffic based on whether an eNodeB, associated with the user device, and another eNodeB, associated with the other user device, are served by a particular network device; forward the voice traffic, as non-local traffic, to another network device, associated with a packet data network, for processing when the eNodeB or the other eNodeB are not served by the particular network device; process the voice traffic as local traffic when the eNodeB and the other eNodeB are served by the particular network device; and forward, to the other user device via the other eNodeB, the voice traffic, as local traffic, where the forwarding is performed in a manner that does not include routing the voice traffic via the other network device.
