[Tamer Mohamed Bayomy]

Dear All,

I have a weird problem with one of Cisco IP phone 7940 that is
registered in 
CCM 4, the user using this IP phone once made forward to another Cisco
IP phone 7940 then he wanted to cancel this forward he is unsuccessful,
can anyone help with this problem as I even deleted the 2nd phone and
still the 1st phone still forwarding the calls can't stop this
forward?!!!

Any help?!!
Regards..
