Possible Cause 4: Wrong bridging adapter is used in combination extension.

What to do: First, unplug the bridging adapter from the wall jack. Then, unplug the phone
from the adapter and plug the phone directly into the wall jack.

If the phone works, there is a problem with the bridging adapter. Replace the

bridging adapter (use only an AT&T 267F2 bridging adapter). If the problem
persists, call the AT&T Helpline.*

If the phone still does not work, call the AT&T Helpline.*

Possible Cause 1: Forced Account Code Entry is assigned to your extension.

What to do: Find out if Forced Account Code Entry (#307) is assigned to your extension.
If it is, enter a valid account code.

If you can make a call, the problem is solved.

If Forced Account Code Entry is not assigned to your extension, go to Possible

Cause 2.

Possible Cause 2: Dial Mode is set incorrectly.

What to do: Find out if you have touch-tone or rotary service and set the Dial Mode (#201)
to Touch-Tone or Rotary as appropriate.

If you can make a call, the problem is solved.

If the Dial Mode is already set correctly, go to Possible Cause 3.

Possible Cause 3: Someone changed the Outgoing Call Restriction setting.

What to do: If you were able to make a call without any trouble before, find out if someone
changed the Outgoing Call Restriction (#401) for your extension.

If someone changed your Outgoing Call Restriction setting, verify that the change
was an appropriate one.
