Test each extension to confirm that the phone system is programmed correctly.
What is needed for the test
A standard analog phone set with a ringer to use as a test set. If the messaging system
●
uses feature phone sets, use a feature set for the tests.
If using an analog test phone, and if the voice boards use RJ-14 connectors with two
●
extensions per connector, then a line splitter might be needed to separate the two
extensions carried by each phone line.
A system manager phone set.

Steps to test the extensions
1
Connect the phone system to the test phone set using a line designated as a
messaging system extension.
2
Confirm that the phone system identifies DTMF dialing through the test extension.
Dial a station phone from the test phone. The station phone should ring.
3
Confirm that the phone system transmits DTMF tones to the test extension.
Dial a station phone from the test phone. Have someone answer the station phone
and enter a digit. You should hear the tone on the test phone. Repeat this test for each
type of station connected to the phone system, for example, analog, feature set, or
operator.
4
Confirm that the test phone can access outside lines.
Dial a number outside of the phone system from the test phone. You should reach the
number.
5
Confirm that the phone system generates rings on the test extension.
From a station phone, dial the extension for the test phone. The test phone should
ring.
6
Confirm that trunk routing is set up correctly for extensions that answer trunk calls.
From a line outside the phone system, dial the number designated for the messaging
system. Answer the test phone, perform a hookflash (timed break recall), then dial a
station phone. Listen for ringing, then hang up the test phone. The call should be
transferred to the station you dialed.
7
Check that trunk routing is set up correctly for extensions that only answer calls from
stations, for phone systems that support trunk routing.
Dial the test phone extension from a station phone. Answer the test phone, perform a
hookflash (timed break recall), then dial a station phone. Listen for ringing, then hang
up the test phone. The call should be transferred to the station you dialed.
