Line Not Registered, Server Not Registered

Using Polycom VVX450.

When I register a line, the line works but a little red X icon shows up next to it.


When I check the line it says:

Line (line name) (Not Registered)

Server ( (Not Registered)


What am I doing wrong? Is there something I need to add to the config file?


Here is the registration config:


reg.2.address="" reg.2.displayName="line x2"reg.2.outboundProxy.address="" reg.2.outboundProxy.port="5090" reg.2.outboundProxy.transport="UDPOnly"

Hello @40love ,


Welcome to the Poly Community.

  • It would be great to check if this is using the UC Software or ObiEdition?(check the FAQ for instructions)
  • Also what software version?(check the FAQ for instructions)
  • Programmed via the Web Interface or are you importing some sort of configuration?
  • Can you share a backup? (check the FAQ for instructions)

Usually, I recommend:
