Procedures for Extension Dialing Between Sites

These procedures outline two different extension dialing configurations that may be used from a particular site to other IP Trunk sites. The first configuration is non-DCS, where one trunk group exists in DEFINITY and is routed through the IP Trunk server to many different IP Trunk locations. The second configuration is DCS, where the trunks are dedicated to specific locations — users are routed to a different trunk group; that is, different trunk ports, within the DEFINITY, based on the digits dialed. The IP Trunk server routes calls based on the ports or lines the call was placed on. Each of these configurations is outlined below and examples are provided.

Non-DCS Configuration

IP Trunk Network Configuration
One DEFINITY Trunk Group to many locations
				DEFINITY
				IP
			All ports in	TRK
			Trunk Group 50
				Switch B
DEFINITY			extension range 4400-4499
	All ports in	LAN/WAN		and 4900-4999
	Trunk Group 50		IP address: 198.152.169.238
IP
TRK
			All ports in	DEFINITY
Switch A			Trunk Group 50
extension range 6500-6599				IP
IP address: 198.152.169.240
				TRK
			Switch C
			extension range 4300-4399
			and 3400-3499
		IP address: 198.152.169.236

In the configuration above, each DEFINITY switch has all of the IP Trunk ports in one trunk group, trunk group 50. Extension calls to the other DEFINITY switches in the network are routed to this trunk group and the IP Trunk server's administration evaluates the dialed strings it receives and routes the calls to the appropriate IP address based on that dialed string.

To arrange a network in this configuration, an administrator will need to know each IP Trunk server's IP address and the range of extensions in the DEFINITY at that location.
