We have a Vodavi phone system in our office. Each phone has 3 lines. When a call comes in to our main line, if it is not answered in 2 rings, it is supposed to be forwarded to our line 2. After 2 rings on line 2, if no one picks up it is to be forwarded to line 3. After 2 rings with no answer on this final line, our voicemail is supposed to pick up. This is not happening though. We have had our clients tell us that the phone rings 10-12 times before going into voicemail. Often, it rings 5 times on line 1 and 5 times on line 2, then goes to voicemail. We are quite possibly losing client calls who do not want to wait for 10-12 rings for a VM to kick in. We contacted Verizon and everything is seemingly correct on their end as far as the sequencing of the rings and call forwarding. They suggested it was something with our phones. We have no idea how to go about changing and/or testing our system. Do you have any thoughts on how our phone system could be the culprit for why the correct call forwarding sequence with Verizon is not "in sync" with our phones? Any ideas for correcting the problem?
