Dear customer,

This is Johnson from Yealink technical support team. Nice to work with you.
For this issue, I have reproduce the problem on local.
I will submit to our R&D team to solved this issue.
Any update, I will note you.

Maybe I'm out of date with my provisioning syntax, but the old way of doing this used to be to set the value to %NULL%. Maybe somebody from Yealink can confirm that's still the case in V81 provisioning though as I have not tested in a long time...

Yes, you are right.
%NULL% means reset value by default.
%EMPTY% means value is empty
For this issue, you can remove ip address via below syntax.
multicast.listen_address.1.ip_address = %NULL%
