VVX 150 Obi won't connect to Google Voice



I have a brand new VVX150 with power adapter and a Google Voice account. 


I have a WRT320N Linksys Router and 10/100/1000 switch. I have connected the cat 5 cord to the ethernet port on the phone. I have entered the phone MAC address on Google Voice with the correct email. The ethernet with the phone has a yellow light, which indicates 10/100 I believe and it blinks intermittently. 


When managing the Desk Phone on Google Voice, the phone is listed as Offline. I attempt to reboot the phone from Google Voice admin and it says "Unable to Reboot Desk Phone."


Based on this -


I went into the router admin and added and enabled these (I believe I did it correctly)

  • Outbound UDP ports range: 19302–19309
  • Outbound UDP ports range: 26500–26501
  • Outbound TCP port 443

I added the Outbound UDP ports ranges under Port Range Forwarding with the IP address of the phone. I added the TCP Port 443 to Single Port Forwarding.


I have tried changing the phone to 10 Full, 100 Full, 1000 Full - many combinations.


Picking up the phone, there is dial tone and when trying to call the display says Server not found. The phone does not ring.


Any advice would be wonderful.

Hello @Coco's Variety ,


Welcome to the Poly Community.


Your Post ended up in the Spam filter and had to be released.


The nature of IP phones is that they provide their own dialtone so even with just a power supply and no network cable it would play this.


Your issue is a network issue and I can only suggest to contact Google support as they can talk you through the options.


Another test could be to dial **9 222 222 222 to check if you hit the Poly PDMS-SP service


Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
