I have CUCM 6 and the 2821 router as a H323 gateway.
My problem is that Call Transfer, Call Hold and Conference not working.
Regardless of whether I call or receive calls, when I want to do a call Transfer, or even call Hold, and Conference, that options are disabled.
Options are displayed on the phone display but can not be used. When I try to do one of these features nothing happens...
Is anybody had similar problems and whether you can give me guidelines on how to solve this problem?
Have a look at this great post from [email protected];
Hope this helps!
