I have an IP office that it seems when you make a call or someone else makes a call, then hangs up, and another person dials out, sometimes it seems they try to grab the line that was just disconnected, but the user hears a busy tone. Is there any way to stop this from happening? When I watch Call Status, the IPO picks up lines in a random order? I also saw a tech tip, Global_IP_Office_Tech_Tip_154.pdf talking about detecting a busy? I wonder if this is my problem. The customer has Centrex lines, maybe I need to adjust the busy tone detection for them?
thanks for any input

This is a little in depth for the user forum, but hit this up in the installer forum for more help. I will PM you as well in the case that you can not get into the installers forum. Are you an Avaya business partner?

We are business partners. I can access the installers forum, I will ask in there
