To support a wide variety of service scenarios including NAT traversal, lawful interception or transcoding, a VoIP provider has to not only use signaling servers but also media servers. To reduce the load on the provider in terms of bandwidth usage and reduce the effects of adding media processing servers in the media path, the media servers should be located in the proximity of the users. In this paper we investigate the possibility of using IP anycast for enabling users to detect and use media servers in their proximity. We propose four different approaches and give a high level evaluation of the pros and cons of each approach.
