I am having trouble with an overflow. I have a site where one of the options is ringing calling group 773. If the group 773 does not answer we want it to go to the operator. i have setup another calling group of 775 and added the operator extn of 400 to it. I have set the overflow of 773 to go to 775. I have set the number based overflow to 99 and the time based overflow to 18 however it just continues to ring the extns in the 773 group. Any idea why it is not ringing the 775 group after the 18 seconds? I used to have it set to 1 for the number and time based and it will ring to the operator as long as all the extns were in use or on DND.
