Testing the DID Trunks
Follow these steps to test the DID trunks:
1.
2.
3.
4.
5.
Work with the central office to check all the DID trunks or have
someone call from the outside to check each DID trunk.
When the first trunk rings, answer it.
Instruct the caller to put the call on hold or put down the handset while
making the next call.
When the next trunk rings, put the previous call on hold and repeat this
procedure until all eight DID trunks have successfully connected.
When all trunks have connected with good communication, disconnect
each call, and have the caller do the same.
