My company currenlty live on Call Manager 4.1(3) using 7940 IP Phones mostly.
We're going to move to 6.1(2) release during this year.
My proctor wants to know, what IP Phones to buy for now to allow them to work
both with 4.1(3) (now) and 6.1(2) (in the future) Call Managers.
What will be your advice ? May be look for another model, other than 7940 Phones ?
