Disabling TLS 1.1 & 1.3 on Yealink SIP-T31P

[Lilpombo]

Hello, everyone

So, how can I disabled TLSv1.1 and TLSv1.2 on my Yealink Phones? I want to use just TLSv1.3...


I added this line on the .CFG arquive:

static.security.default_ssl_method = 5

Number 5 activates TLSv1.2; I made a Nessus scan and the Telephone appointed vulnerabilities on TLSv1.1 and TLSv1.2 ciphers. So, the telephone is using the TLS 1.1, 1.2 and 1.3 too;


But... It doesn't works, the telephone didn't disabled TLSv1.1 for using only TLSv1.2; So, now I want do disable both... How can I do this? I didn't find this in the documentation...
