External Hotline (#311)
Description
Related Features
This procedure applies only to standard phones.
This System Programming procedure identifies an external hotline extension.
When a user lifts the handset of an external hotline, a predetermined outside
number is dialed automatically. The external number might be, for example, a
frequently-called service bureau. The external hotline must be a standard
phone, not a system phone.
After you identify an external hotline extension, you must store the external
phone number for the hotline extension as Personal Speed Dial code 80. Both
procedures are included in “Programming” on the next page.

Use Hotline (#603) to identify an internal hotline extension.
Use Line Assignment (#301) to assign outside lines to the external hotline
extension and Automatic Line Selection to set the extension to select
outside lines first.
If your use of the external hotline requires immediate dialing of the
programmed number, dedicate a line for use by this extension (do not
assign the line to any other extension or use the line for any other
purpose).
You can set Line Ringing to No Ring for all lines assigned to the external
hotline to prevent incoming calls from ringing at the extension.
Make sure there are no call or line restrictions assigned to an external
hotline because that will prevent the outside number from being dialed. See
Outgoing Call Restriction (#401) and Line Access Restriction (#302).
Do not use Station Lock at an external hotline because it will prevent the
outside number from being dialed.
Remove external hotlines from Night Service Group Extensions (#504),
Calling Group Extensions (#502), and Hunt Group Extensions (#505).
Do not assign Forced Account Code Entry (#307) to the external hotline.
Considerations

■
Under certain conditions of heavy telephone usage, the external hotline may
be unable to dial the programmed number immediately (for example, if
many of the standard devices connected to your system dial out at the same
time). See “Using” for more information.
A standard phone without a dialpad is recommended for use as the external
hotline.
You can identify several extensions as external hotlines.
Do not assign an external hotline to extension 10, 16, 22, or 28 (which are
reserved as power failure extensions).
