I am new in VoIP domain. We have cisco router 1760 with FXO and call manager 4.0 . When somebody call from outside the company the regular phone rings 3 times before the greetings display. I searched on both router and CCM, but i can't find where i can decrease the number of ring times. The greeting is recorded on cisco unity voice mail.
Also when we press 9 on cisco 7940 we get connected directly to the pstn line, the problem is when we dial a number it takes a long time before it connected to the destination number.
Could somebody please Help.
