I have a user that is in one pbx and has an ext in another pbx on our network and wants to be able to call forward one phone to the other when at either location....example.....I am in pbx #1 and I am leaving to go to my desk at pbx #2, I want to forward all of my calls from my phone on pbx #1 to my phone on pbx #2...both systems are networked and have 5 digit dialing between them.....what is the best way to do this??????
