Hi, I'm a new user and I have some trobule with extensions.
I have three lines in my sofphone, and I'd like to transfer incoming calls from one of this lines to onether one.
(I've Express talk as softphone)-
I thinked i could do this with extensions, but I don't know how to associate the extension to a number 
I click on "ADD EXTENSION" but then I don't know what to do?
Can somebody help me?
Thaaaaaaaaanks
