External Hotline (#311)
Use this feature to identify 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 single line telephone, not a system telephone, and should not have a dialpad.
After you identify an external hotline extension, you must store the external telephone number for the hotline extension as Personal Speed Dial code 80.
- 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 tip/ring devices connected to your system dial out at the same time).
- You can identify several extensions as external hotlines.
- Do not assign an external hotline to extension 10, 11, or to the first two extensions of any 206 or 308EC module, which are reserved as power-failure extensions.
- Use Hotline (#603) to identify an internal hotline extension.
- Use Line Assignment (#301) to assign outside lines to the external hotline extension, Pool Extension Assignment (#314) to assign pools to the external hotline extension, and Automatic Line Selection to set the extension to select outside lines or pools first.
- If your use of the external hotline requires immediate dialing of the programmed number,
assign a line for use only by this extension.
- Set Line Ringing to No Ring for all lines or pools assigned to the external hotline to prevent incoming calls from ringing at the extension.
- Make sure there are no call, line, or pool restrictions assigned to an external hotline.
- 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.
