1. A system for compressing a VIA field in a session initiation protocol (SIP) signaling message, the system comprising:

  • a network device situated along a network path, the network device configured to process SIP signaling messages; and

    a compression module configured to be executed by the network device, wherein the compression module receives an SIP signaling message, compresses the SIP signaling message by removing redundant information in the VIA field and retaining non-redundant information in the VIA field, and appends at least one parameter in the VIA field to identify a portion of redundant information removed from the VIA field, the redundant information comprising redundant address information of each intermediate address along a path traveled by the SIP signaling message.
