M4 Origination Points

Origination Point is connection from some initial entity (device/line/trunk/provider/supplier/etc) where call starts/originates.

Call comes from Origination Point and goes to Termination Points.

Why there is no Register option on Origination Point?

Registrations are needed when Dynamic IP addresses are used. Dynamic IP addresses are very common on Retail business, but not on Wholesale. That is why M2 does not have such option.

You as a system owner can allow traffic from IP:Port:Technical Prefix. This is enough to receive traffic from any OP.

Subnetting

It is possible to set subnetwork for Origination Point. Subnets allow you to have single Origination Point for multiple IP addresses. Instead of IP address, you can set subnet in IP Address input field. Subnet should be written in CIDR notation (for example 192.168.0.1/28). When subnet is used in Origination Point, all calls coming from that subnet will be authenticated.

You can use online subnet calculator to check IP addresses for given subnet.

IP range

If you need to set multiple IP addresses for single Orignation Point and Subnetting does not meet your needs, then you can set IP ranges. Ranges are written in the following format:

xxx.xxx.xxx.xxx-yyy

When IP range is used in Origination Point, all calls coming from that IP range will be authenticated. For example, if we have IP range 192.168.0.101-150, then all IP addresses starting from 192.168.0.101 to 192.168.0.150 will be authenticated (50 different IP addresses are allowed to call to this Origination Point).
