III. Configuring country and area codes for devices
You can configure country and area codes on the LS for its administered devices based
on their geographical locations.
Note:
On the XE IP PBX, you can configure only area codes for devices. When a call involves
devices with different area codes, the dialed number must include the area code. The
same applies when a call involves different country codes.
Perform the following configuration in LS-GW or LS-OFFICEGROUP view.
Table 1-7 Configure the country/area code of the device
Operation Command
Configure the country/area code area-code { region-code [ nation-code ] }
Delete the country/area code
undo area-code
By default, neither country code nor area code is configured for the gateway or office
group.
Note:
XE supports a combination of country code + area code + subscriber number within 31
bits.
If country code and area code have already been configured on the device, the
character string of subscriber number or route number cannot begin with country code,
area code or the combination of country code and area code.
1.4 Rule-Based Number Substitution
As the name implies, rule-based number substitution is to substitute a calling/called
number based on substitute rule.
You can apply rule-based number substitution to the LS globally, to an intra–LS domain
device, or to a specific number. In addition, you can use it independently or in
conjunction with location-based number substitution or voice VPN, depending on the
desired dial policy.
