I have a norstar m7208 phone and I want to use it as a standalone normal phone set, is it possible ?

This is Caller ID log

FEATURE 812 View Call Log
FEATURE 813 Manual Call Log
FEATURE 815 Deletes Call Log Items

To have no log see your office administrator or call your local tech to De-program your phone from the system log.

This is tech side of programming and not Admin, if you don't know config password or how to program then call a tech.
If you do know then:
First find out what line #, do F*0 then press the button and note the full number on the display.
i.e. Line 5 in programming is Line 005, 025 or 031 depending on software version.

Sets/LineAccess/LineAssignment/Show line ***/Change to Appear Only or Not Assigned.

Press FEATURE * 501 to choose English as primary language.

No, the M7208 is a propriatary set which requires the PBX to function, whereas the aastra phone is a stand alone set which requires a standard telephone line and a power source.

Is set relocation on?
If not then probably what has happened is that the new station port does not have ringing programming of the old port.
if you know how to do this go into riging programming of the set and activate it

Any other phones on system with the problem?

DTMF or touch tones are generated through the trunk card(s) of the sytem problem. Chances are there may be more then one phone that has a problem.

Also on the outside of things, just try calling the same number from a different phone on the system, and if possible try using the trunk/line that you did with the m7208 in question, same problem? If yes possible trunk issue. If no, then try another phone where the problem set is plugged into.
Another thing you can try is call another service that uses a touch tone menu, using the phone in question, see if you have the same problem.

My BT Meridian compact does not ring after it powered down in a thunder storm. The lines flash and can be answered as normal just no ringing sound

Have you tried:

Feature **23646 password 23646 (if you phone admin hasn't changed this) and then select set day& time then change there

There is a built-in feature called Set Relocation. Check with your system administrator to make sure this feature is set to No. Then you can swap phones without a problem. Good Luck!

Increase the contrast of display of ur phone it might fix the problem
