I recently upgraded to software ver 6.1 as well as the addition of a Callpilot 100. Right now I have 4 trunks that are set to appear and ring on various sets. What I need to happen is to have the calls go to the Callpilot after going unanswered for seven rings. Everything works with the exception of one line. It has a rollover feature that rolls it to the first trunk line. When someone calls the line that has rollover and it is busy it seems to immediately get routed to random voicemail boxes. I believe that the problem lies somewhere in the number of rings before answering. I have changed various settings in the Callpilot as well as the system transfer settings, terminal and sets forward settings etc. I need to resolve this as we plan on ordering rollover or hunting for all lines.
