Phone System Wiring:


You will need to connect the phone lines into the phone system from your phone company’s phone line box with an individual wire for each phone line (single pair/2 Conductor should be fine – 2 pieces of copper on the phone jack).


You will then need each phone to also have an individual home run wire run from an available IP Office digital station port to the desired location of each phone using a minimum of a 2 Pair/4 Conductor wire (meaning when you look at the phone jack you should see 4 pieces of copper).

Avaya 9500 series “PLEASE WAIT” on the screen notes:


When you connect the 9500 series phone to the IP Office it will show the release on the screen.   My experience has been that release .55 & .60 9504 phones worked and upgraded/loaded files on my 7.0(36) IP Office and after the upgrade if you go to advanced and self-test on the phone the phone will show that it upgraded to release .39 in my experience on my 7.0(36) IP Office processor.  Release .59 9504 phones did not upgrade/load files on my 7.0(36) IP Office processor and just showed  “PLEASE WAIT” on the LCD screen.


Work around fix – I upgraded/loaded files from a working 9508 or a 9504 Global Icon phone onto the extension on my 7.0(36) IP Office system until the 9508/9504 Global Icon phones worked and then connected the release .59 9504 phone to the same extension port and the release .59 9504 phone worked from the loaded 9500 files on that extension port and remained release .59 per the self-test notes on the phone.  However if you reboot the system the .59 9504 phones will again say, “PLEASE WAIT” on the phone and you will have to swap phones on other 9500 series working system extensions to remove the  “PLEASE WAIT” message on your phone again.
