Abstract
The invention relates to sending media packets, such as SIP or RTP, via a media forwarding element which includes an anycast interface having an address shared with other media forwarding elements. If network topology changes or a media forwarding element becomes unavailable, then anycast messages may be routed to a different media forwarding element sharing the same anycast address. The new media element can then take over handling of the call from the first one.
