Caller ID not displaying on incoming calls until after I answer the phone

When receiving incoming calls on our Yealink t33g phones the caller ID display is showing the phone number of the caller, and as soon as I pick up the phone it will display the correct caller ID name. 

 

For example, we get a random call which will show the caller ID name as their phone number such as xxx-xxx-xxxx and then it will switch to "Wireless Caller" or whatever the correct caller ID name is after the phone call is answered. 

 

Anyhow know how to resolve this issue to actually display the caller ID name before I answer the phone? Thank you.

hi @red10001 

 

Do your yealink t33g desk phones the latest firmware installed?  As of 9/24/2025, the latest 8/17/2025 firmware available is 124.86.3.12.

the caller-id number is sent by the caller's telcom provider.  in the u.s., the caller-id name is looked up by the call receiving telecom provider or is taken from the callee's contacts.

 

please see zoom support article.

Yes, the latest firmware is installed.

It turns out the Zoom tech support had to make some type of setting change described as "OP Enablement to Disable Manage Caller ID," which resolved the issue.
