MG 1000T Example - PRI call to IP Phone					WAN
1.	Incoming ISDN D-Channel DID message to MG 1000T
2.	MG 1000T Core converts to CDP call to Virtual Trunk/SS.
3.	MG 1000T SS requests address for CDP DN from NRS.			7
4.	NRS provides address of GW SS endpoint of CS0.
				6
5.	Signaling Server directs call to GW SS/CS0.
6.	CS0 tells IP Phone to ring and sends Alerting to SSC.		CS 1000E
7.	IP Phone off-hook to answer; message to TPS SS/CS0.			10	IP Phone
8.	CS0 sends connect to SSC using GW SS and MG 1000T SS.
9. Primary Controller cuts through media between PSTN/DSP and IP Phone
	and sends Connect message to PSTN.
10. Media path flows between DSP and IP Phone.
