Are the phones registered and is there a user logged in?
Do they have appearance keys?
Did you monitor the problem?

yes i created a user and extension number which is the same configuration i did on the working one, and also have apearance keys which a= is by dailing local extensions.. and until now im still looking for any other way to solve this problem..

It would be very helpfull if you can describe what is happening and what you see in monitor.
Only stating it isn't working is not very informative.

When a phone is off you can press and hold the red and green keys.
Then you should be shown the firmware versions.
Write those down then compare between each other.

When you dial and the call fails what is displayed on the phone?

Menu -> Settings -> About Avaya one-X shows the software version.

thanks guys we solved it by updating the firmware of the phone, from the system menu in avaya manager i put the IP Address of the System Unit in the field HTTP as a server for uploading data to phone to make it upgrade... then the problem solved.. thanks again..
