Numeric addresses
A numeric address enables subscribers to address any Octel Unified 
Messenger recipient in an organization. 
Every Octel Unified Messenger recipient must be assigned a unique 
numeric address. The numeric address allows a subscriber to send a 
message to any recipient from the telephone user interface without having 
to know the recipient’s location. The Exchange directory ensures that all 
numeric addresses are unique, and makes them available to all locations 
within the organization. 
It is recommended that all numeric addresses have the same number of 
digits. However, the length of a numeric address must not be the same as 
the length of the local mailbox number in any voice mail domain within 
the organization. If the lengths conflict, Octel Unified Messenger cannot 
distinguish between a local mailbox number and a numeric address. It 
assumes the address is a local mailbox number. To avoid conflicts with 
the length of any local mailbox numbers, leading digits may be added to 
numeric addresses.
Organizations may choose to use telephone numbers for numeric 
addresses because they are unique. Other possible schemes include:
n
A geographic location code associated with a local mailbox 
number.
n
Social security numbers.
n
Employee numbers.
n
Short numeric addresses, such as “55” for a Help Desk, or “1” for 
the CEO’s office etc.
