Running cme 3.3 on 2811 with (C2800NM-SPSERVICESK9-M), Version 12.4(3b). Code in 7912's is CP7912060100SCCP050315.sbin.
If a 7912 user receives a call and then does a transfer to another local IP phone. The transfer is sucessful, but when they pick up the hand set to make another call there is NO dialtone. The user then has to tap the "new call" softkey to get dialtone. On top of that the very next incoming call shows ringing on the phone display but does not ring audibly??.
I have "auto-line 0" set on the phone but that is the default. The problem only seems to happen after a transfer and seems to happen on all 7912's. Also I tried downgrading the code from CP7912060100SCCP050315.sbin to CP7912060000SCCP050124A.sbin but the 7912's display a message "need ver >=6.1" keep what they have for code?? Any ideas??
