Multi Line Telephone Systems

The Grand Junction Regional Communication Center recently converted our 9-1-1 delivery system from analog to digital. Along with the Colorado Public Utilities Commission, we are encouraging organizations with multiple telephone extensions to ensure their systems are correctly routing 9-1-1 calls to the center. The interaction between the new technology and improperly configured telephone systems could cause a delayed emergency response by not providing location information when the call is placed to 9-1-1.

This update only affects those with multiline telephone systems or primary branch exchange systems, such as schools, hospitals, government agencies, or large office buildings. However, even smaller medical facilities or care centers should test their systems to ensure that they are programmed correctly and can reach 9-1-1 in an emergency. Those affected should contact their information technology department or company responsible for their phone systems to ensure proper programming, to include testing from remote locations to ensure all extensions can reach 9-1-1 and are sending correct location information. Test calls should be scheduled by calling 970-242-6707 and asking to test. Please do NOT call 9-1-1 to test without first calling the non-emergency number to ensure it is a good time to make a test call.
