hi dselden63,

 

begin by adding your phone to the Zoom web portal

Note: Make sure to add your phone to the Zoom web portal before powering on a new phone for the first time or performing a factory reset on a previously-used phone. You can find your phone's model name and MAC address on the label located on the bottom or back of the phone.

Thanks Ellot- I have done 10+ factory resets, added the phone to Zoom and tried to auto provision at least a dozen times...still "no service"

Hello @dselden63 

 

For ZTP to work on yealink phones,

make sure you have Ports 80,443 open to http://rps.yealink.com

 

Please see this article for more ports to whitelist, if your network is very restricted ( share with your network person 😞

 

Let us know how that goes

As above -

- check firewall to see if blocking any of the needed traffic

- verify local dhcp not providing parameters overriding the yealink settings

- verify have yealink firmware as specified as needed by zoom (I've not seen this issue on yealink desktop phones, but could happen if is an old phone that has been powered off a long time perhaps?
