I have a panasonic phone system D816 and I need to know how to unlock long distance on all extension and all lines. Can someone point me into how to do this?

Right now only two extension and line 4 is opened for long distance.


Thanks in advance for your help.

When you read the manual and get into programming, compare the class of service and restrictions of the two extensions that work with the COS of the ones that don't. The COS also gets applied to lines, so you'll start to see a pattern.

Of course, TX being a large state, you ought to be able to find an older Panasonic dealer who would know how to do it.
