Hello, I am from Mitel world trying to start servicing Nortel BCM50. There are 2 lines (073 and 074 appearing on 2 extensions 2225 and 2226). Ideal scenario - they both ring on both sets, if no one answers after 6 rings - 073 should go to 2225 voicemal box, 074 would go to 2226 VM. But somehow they both go to main general mailbox after 4 rings. I can make them transfer to the extensions through CallPilot CCR after 3 rings, but if I put 4 or more rings on CCR - default voicemail overrides it. Is there a way to stop them from going to default voicemail and how to increase the amount of rings before the VM in general?
