When turning off-hook an IP phone, it start playing the dial tone. After the Timer_Offhook_To_First_Digit_msec (CCM V3.2 default 15 sec.) if no digit are typed, the phone plays a busy tone for 30 sec and than hangs-up the line automatically.
I would need to know if there is a timer to adjust the 30 sec timeout. I didn't find any on CM Service parameters.
Many thanks for your attention/aid
