    A L{Via} is a SIP Via header, representing a segment of the path taken by
    the request.

    See RFC 3261, sections 8.1.1.7, 18.2.2, and 20.42.

    @ivar transport: Network protocol used for this leg. (Probably either "TCP"
    or "UDP".)
    @type transport: C{str}
    @ivar branch: Unique identifier for this request.
    @type branch: C{str}
    @ivar host: Hostname or IP for this leg.
    @type host: C{str}
    @ivar port: Port used for this leg.
    @type port C{int}, or None.
    @ivar rportRequested: Whether to request RFC 3581 client processing or not.
    @type rportRequested: C{bool}
    @ivar rportValue: Servers wishing to honor requests for RFC 3581 processing
    should set this parameter to the source port the request was received
    from.
    @type rportValue: C{int}, or None.

    @ivar ttl: Time-to-live for requests on multicast paths.
    @type ttl: C{int}, or None.
    @ivar maddr: The destination multicast address, if any.
    @type maddr: C{str}, or None.
    @ivar hidden: Obsolete in SIP 2.0.
    @type hidden: C{bool}
    @ivar otherParams: Any other parameters in the header.
    @type otherParams: C{dict}

        Set parameters of this Via header. All arguments correspond to
        attributes of the same name.

        To maintain compatibility with old SIP
        code, the 'rport' argument is used to determine the values of
        C{rportRequested} and C{rportValue}. If None, C{rportRequested} is set
        to True. (The deprecated method for doing this is to pass True.) If an
        integer, C{rportValue} is set to the given value.

        Any arguments not explicitly named here are collected into the
        C{otherParams} dict.

        Default request handler.

        Default behaviour for OPTIONS and unknown methods for proxies
        is to forward message on to the client.

        everything.
