RE: About HTTPS certificates and trust
(05-24-2018 08:41 AM)TrK Wrote:  Our provisioning web server have Rapid SSL RSA wildcard certificate, which is trusted by default Yealink phone. Our DHCP server send OPTION 43 with https link. Everything is working good - we unbox new phone, connect it to network and viola, not need to logon on phone`s web interface.

But our RSA certificate will be expired soon. We decide to switch to Let`sEncrypt ECC certificate. As i can see, Yealink phones by default have root LE cert "DST Root CA X3", but not have intermediate "Lets Encrypt Authority X3".

What should i do with that? Set security.trust_certificates = 0? Add this Intermediate CA certificate to Trusted?
But how new phones will get this settings without access to provisioning web server?


And another related question, about format of
Code:
trusted_certificates.url
.
What is solution when i need to add two (or three, or four) root certificate to Trusted? Should i add all to one file, like in chainfile? But this certs are from different CA.

Dear customer,

For this case, please find my answers below:
1. The root CA is exist, so please ask server provider to send sub-CA to the phone when it asks for the authentication
2. For the parameter, please create seperated parameters for different CA:
static.trusted_certificates.url = http://10.91.80.50:8080/1.cer
static.trusted_certificates.url = http://10.91.80.50:8080/2.cer

Any question, freely to let me know.

Regards,
Travis
