Yealink T48g Desk PhoneThe buttons on office phones can be very handy as shortcuts.  Buttons are usually set up as BLF (Busy Lamp Field) or extension monitor keys, Speed dials or  Login to Queue buttons.

  2. Navigate (using the arrow keys) to the "Features" choice and select
  3. Choose choice 4 – DSS keys
  4. Select the button you'd like to setup 
  5. Make changes as appropriate and
  6. Save

  3. Go to the BLF (Busy Lamp Field) tab along the top
  4. Make changes as appropriate

Installing a Colony Phone System

We've been providing Hutterite colonies with phone systems for a couple years now and decided it was time to start providing a How-to manual.

Hutterite colonies are different from our normal urban phone system installs in that the colonies themselves do most of the work.  As such they need a deeper understanding of the technology, design and implementation of the system then do most of our other customers.  

There are 8 major components to Colony phone systems which are common to most other larger commercial installs as well:

  1. Internet Connection
  2. SIP base Phone Company
  3. Point to Point wireless network to connect buildings
  4. Internal Building Wiring to connect phones
  5. Internet Security Gateway (aka Firewall or Router)
  6. Church
  7. Phone System Server
  8. Phones
