Avaya phone constant ringing nonstop

remove the power cable and put it back

Is this an IP Office?
This is how it works. For some reason the IP Office waits for teh first 2 rings to get caller ID, and then lets the call ring in.

At ext 10 or 11
press feature 00
LEFT intercom
LEFT intercom
Right intercom
enter extension number to change ringing on
the line buttons will light up if you touch the line it will change the flashing and the ring style.

Once done, press feature 00

Repeat for all phones.

Did you program teh phone as a door phone 1 or 2? Then you will need to program the phones you want to ring itnto teh Doorphone 1 or 2 ring group.

Yes, Call D

The partner voice messaging system would be a card that looks like the processor card , It should also have a green sticker on the face of it identifing it as such.

Yes you can have the 2 lines answered by a particular mailbox instead of the AA greeting.
Would need to know the model of the voicemail system that is installed to see if there are more than 1 AA menus.

Your system lost its programming. It will need to be reprogrammed completely. The lines are ringing on the extensions where I voicemail is, unplug voicemail and at least lines will ring in correctly.

Sounds like you changed your line selection. Changing line selection on a Partner system is done on either ext 10 or 11.
At one of those ext's press the feature key and "00"
Next press the left hand intercom twice
The display should say system programming

Press the right hand intercom once. The display should say Centralized Programming.

Enter in the extension number that you want to program.

enter **
press the lit line in the order you want the to be used, i.e. line 2 then line 3 then line 4 etc.
enter ** when finished with line selection
.
Press feature "00" to logout
Hope that helps

Glad to hear it
