# Feature Access Codes

## Description:

Feature Access Codes (FACs) are special sequences of characters that users dial from a telephone keypad to invoke features. For example, a user might press *6, following by 2023 to forward all incoming calls to extension 2023.

FACs are most often used from analog phones and from single-line digital or IP phones while users of multi-line phones select soft keys or programmable keys to invoke the same features. The same FACs are used by all phone types with certain exceptions for SIP devices; see SIP Device Support for Feature Access Codes.

FACs are enabled on all phones unless explicitly disabled by de-programming ("blanking out") the assigned characters in the Feature Access Codes form. All FACs are customizable.

## Conditions and Feature Interactions

- See the Feature Access Codes form.

- SIP devices support a subset of the feature access codes that user can dial to invoke call control features; see SIP Device Support for Feature Access Codes.

## Programming

- Feature Access Codes form

- Assign codes to features as required.

## Device Support

Except for SIP devices all FACs are available to all phones regardless of type. See SIP Device Support for Feature Access Codes for exceptions.

## Operation

In general, FACs are dialed immediately after a phone is taken off hook. Some, such as Call Park are vaild only after initiating a transfer by softkey or feature key press or hookflash (analog phones). See the System Features section for feature-specific operations.
