I am sure this is a dumb question but I am getting nowhere
I need to upload a root bundle with LE Root and Intermediate to a voice proxy for TLS. I am unsure of the exact format, docs just say pem. This website contains an example of a root cert bundle I know works, I just need the LE equivalent
Obtain the signed certificate from the Certificate Authority (CA). You might also receive a certificate
trust chain if the CA did not directly sign the certificate. The certificate trust chain might be provided
as a separate file or it might be concatenated directly onto the signed certificate.
If the signed certificate is not in a PEM-encoded format, reencode the certificate in the PEM format
openssl x509 –in input.der –inform DER –out output.pem –outform PEM
