All of our offices have avaya IP office and all of our hardware is the same but something is different with this particular office @ 10.33.33.0. They can dial everyone's office extension except one particular office at 10.2.2.31. What sort of things should I look for? The system has been rebooted, you can dial the office @ 10.33.33.30 from any other office but you cant dial to office at 10.2.2.31 from 10.33.33.30
