Some users got used to dial in following manner - they enter number on dialpad and then pickup headset. After 7911 phones been replaced with 6921 this technique doesn't work anymore. After picking up headset phone complains about reaching maximum nuber of calls per line, though there was not active calls at all.
CUCM System version: 7.1.4.10000-4 Unrestricted
Phone load SCCP 9.2.1.0
Any ideas?
