I have CUCM 6.1.2 and added Linksys IP Phone SPA922. it registered and I can make calls, do transfer during the call, make a conference but I have problems with all kind of call forwarding. When I go on wesite of the phone and put some number under cfwd all dest, I cann't reach my number any more. On the phone LCD is displayed Calls forwarded, but they are not.
I tried also with cfwd no asn and cfwd busy and call forward doesn't work. In these cases I can reach my number, but call is not forwarded.
Also, I tried to do the forwarding through softkeys on the phone, but without any luck.
Do you have any idea, what could be the problem? and how can I make it work?
