Hi @gary, thanks for the info. We already contact the Yealink Support and they already answered, they told us that we were using discontinued models of Yealink Phones (SIP-T32G, SIP-T28P); due we are using the latest version of OpenVPN (2.4.6) & Easy-RSA (3.0) the supported models are: T2P, T4G, T4S, T5S.
We will release the next version of OpenVPN add-ons that allows you to download configurations suitable for upload to a Yealink phone the next week.
