Important: in WMS 5.0X Custom certificates are accepted only with signature algorithm not lower than SHA256.
Intro: What is SSL and an SSL Certificate
Secured Socket Layer (SSL) is the technology that ensures that data between two machines (in our case – a browser/ phone and PBX) is transmitted securely in an encrypted connection (HTTPS).
An SSL Certificate is a digital certificate that confirms the identity of a website. It is usually represented as a pair of small text files with encrypted data (Certificate *.crt and Private Key *.key).
To implement SSL on your PBX in the absence of access to Wildix certificate-updater service, you need to:
submit a CSR (Certificate Signing Request) to an SSL Certificate Provider (Certification Authority) and get an SSL Certificate
create /wiki/spaces/DOC/pages/30283909 by you own. These certificates are easy to make and they are free. However, they do not provide all of the security properties that certificates signed by a CA aim to provide.
Then you need to import certificate and private key to PBX.
