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} �UDPNFc K s� || _ || _|| _|| _|| _|| _|du r%tjdtdd� d| _ d| _ n |du r0d| _ d| _ n|t u r;d| _ d| _ n|| _ d| _ || _ | | _ | | _dS )a( 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.
