Abstract: The present invention discloses a clip retainer which includes a top surface having a groove and a bottom surface which has stopping ribs and a barb formed between the stopping ribs. The top surface and the stopping ribs of the bottom surface clamp a flange of a clip. A slope of an inclined plane of the barb in a slide-in direction of the clip is smaller than that of an inclined plane of the barb in a slide-out direction of the clip. Based on the above structure, the clip retainer can meet the function requirements of small slide-in force and large slide-out force of the clip and has a simple structure. Furthermore, the clip retainer can produce repeated insertion and extraction deformation and is very reliable to use.

Abstract: Systems and techniques are provided for supporting multi-party meetings over a telecommunication network. In one implementation, meeting status information may be provided to a client for display on a user interface. The meeting may involve a voice connection between the parties that is established over a Signaling System 7 (SS7) network. Status change information may be received over the SS7 network, and the status change information may be forwarded to the client for updating the user interface display. Other implementations may involve receiving a meeting group identifier via a signaling network and retrieving routing numbers associated with the meeting group identifier. Calls can be initiated using each of the routing numbers, and the calls may be connected together to establish a conference call.
