FreePbx // duplicate IP address with Polycom DEvice IP Phone 550


I m using ‘’ FreePBX" sangoma with Polycom Phone 550 , since 1 week i face an issue with error message (duplicate IP addreess with Mac address…)

The problem is that there is no Duplicate Ip adress at all , there is a specific VLAN and when i put a fix IP address i face the same issue .

Please i need your support .

Best regards

if you’re using a mix of static and DHCP addresses then it’s very likely you do have a duplicate IP address. Double check all of your DHCP pools to make sure they do not overlap any of your IP addresses.
