Integration in the MX-ONE Service Node

The SIP extension is fully integrated in the MX-ONE Service Node architecture. This feature allows the SIP terminals to call and be called, as any other type of extension in the MX-ONE Service Node.

For Non-Gateway (NGW) calls between two SIP terminals, the media are directly transmitted from one endpoint to the other.

For Gateway (GW) calls to and from a SIP terminal, the media is transmitted through the MX-ONE Media Gateway. A call between an H.323 and SIP extensions is a GW call.

A detailed explanation of every component needed to make the SIP extension work, is given in the following subsections.
