2.2 Making Calls
2.2.1 Dialling an Extension
In most configurations, dialling an extension simply involves dialling the extension
number directly.
On digital phones, the waiting time after dialling certain numbers may be several
seconds. To complete dialling without waiting, press # or SEND after dialling.
Digital phones may have an address book for shortcut dialling.
The switchboard phone and other digital feature phones may have marked shortcut
keys (DSS keys) for direct dialling to extensions.
2.2.2 State of an Extension
Busy, call waiting enabled: caller will hear normal ring back and called party will
see/hear notification. Called party can place current call on hold or end current call
and pick up second call, or proceed to unavailable state if not answered.
Busy, call waiting disabled: caller will be redirected to voicemail if enabled, or follow
me settings.
