We have an AT&T Avaya Partner II phone system. How do we extend the number of rings before the voice mail picks up?

Unfortunately on the earlier Partner systems they only gave you the option of either 2 rings (immediate) or 4 rings (delayed) . The program number to look at the setting on yours is # 506.

Hi i have a lucent phone partner-6. how do i turn the ringer off

Go to the system attendant and have them perform Centralized programming to change your ringing. It's a simple procedure, but it must be done with a better phone from extension 10 or 11.

Mls-12d, how do I change the time on the display.

Changing the time 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
enter in "#103"
the display should say system time and the current programmed time
enter the new time in 24 hour format
press feature "00" to logout
