M4 Termination Points
Description
Termination Point is connection to some final entity (device/line/trunk/provider/supplier/etc) where call will be terminated.
Call comes from Origination Points and goes to Termination Point.
Termination Points are assigned to Dial Peers.
Termination Point Settings
Act as Termination Point - turns on/turns of Termination Point. If selected No and saved, all settings of Termination Point will be erased.
Active - activates/deactivates Termination Point.
Tech. Prefix - technical prefix that is added to destination number when dialing through this termination point. Tech prefix can also be used to modify outgoing number by using Tech Prefix rules
Tariff
Capacity - limits the number of concurrent calls to this termination point.
Source (CallerID) Allow - regular expression (regexp) for CallerIDs that are allowed to go through this termination point (use regexp .* if you want to allow all CallerIDs to go through this termination point).
Source (CallerID) Deny - regular expression (regexp) for CallerIDs that are NOT allowed to go through this termination point (leave empty if you do not want to disallow any CallerIDs).
Register - should we register the provider?
Login/Username - username if your provider asks for it.

Subnetting
It is possible to set subnetwork for Termination Point. 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 call is routed through Termination Point which uses subnet, random IP address from that subnet will be chosen for outgoing call.
You can use online subnet calculator to check first and last usable IP address from given subnet.
IP range
If you need to set multiple IP addresses for single Termination 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
Note that you can set range only for last octet in IP address.
When call is routed through Termination Point which uses IP range, random IP address from that range will be chosen for outgoing call. For example, if we have IP range 192.168.0.100-150, then random IP address from range 192.168.0.100 - 192.168.0.150 will be generated.
