established by the International Telecommunications

PBX Access Code The access code required to enter the site’s PBX
system.
Country Code The country code for the country in which the site is
located.
Area Code The city or area code for the site. Do not include a
leading zero. For example, the city code for Paris is

# of Digits in
Subscriber Number
The number of digits in a phone number. For
example, in the United States, subscriber numbers
may have seven digits or ten digits depending upon
the region.
Assignment Method The ISDN number assignment method for the site.
Possible values include:
• No Auto Assignment. Select this option when
ISDN numbers are not assigned to IP devices.
• DID (Direct Inward Dial). Select this option when
you assign a range of phone numbers received
from the telephone company service.
• Gateway Extension Dialing. Select this option
when you have a single gateway phone number
and a range of extensions (E.164 aliases) that are
internal to the company. In this case, calls go
through a gateway. Endpoints are differentiated by
the extension at the end of the dial string.
When a site is assigned an automatic assignment
method, devices without an ISDN number are
assigned one when they register. These numbers
allow inbound calls to reach specific video endpoints.
After an ISDN number is assigned to an endpoint, it is
reserved for use as long as that endpoint remains
registered with the RealPresence Resource Manager
system.
Note
If you do not assign ISDN numbers automatically, you
cannot call IP-only endpoints through an ISDN line.
Territory Assigns the site to a territory, and thus to a
RealPresence Resource Manager system.
Location Specify the geographic location of the site either by
longitude+latitude or country+city.
