Programming Basics
Caller ID
Caller information (telephone number) is furnished to MLX display telephones by
an 800 GS/LS-ID module using the LS (loop-start) option. This allows customers
to screen calls prior to answering the phone, as well as providing calling party
information for use with various applications. This function is only available when
the customer subscribes to caller identification service from the telephone
company, if the telephone company supports that service.
Shared System Access (SSA)
A telephone may have up to 27 Shared SA Shared SA buttons to expand extension
coverage.
Authorization Codes
The Authorization Code feature allows you to make calls using your calling
privileges when you’re dialing from an extension other than your own. When you
enter your authorization code (ranging from 2 to 11 characters and unique
across the system), the privileges and restrictions assigned to your home
extension override the current restrictions at the host extension. This includes toll
restriction, outward restriction, Facility Restriction Level (FRL), Allowed Lists,
Disallowed Lists, Night Service Exclusion List, and Dial Access to Pools. All other
functions on the telephone are those of the local telephone, not the home
extension.
Authorization codes can also be used for the purposes of call accounting
through the SMDR printout. The SMDR account code field can hold the
authorization code extension number or the authorization code itself.
Direct Voice Mail
If your company has voice mail, this feature allows you to dial a co-worker’s
voice mailbox directly without ringing that person’s extension. Direct Voice Mail
is especially useful for transferring calls when a co-worker is not available.
Additional Features
The status of Leave Word Calling (LWC) and Privacy are retained across cold
starts.
Caller ID (CLASS
SM
ICLID and PRI) are available on primary coverage and return
from transfer.
