Upload TLS certificates to the PBX

Yeastar P-Series Software Edition supports TLS protocol to secure SIP messaging. Before using TLS protocol, you may need to upload a TLS certificate.

Background information

With TLS protocol enabled on the PBX, a TLS certificate may be required in the following situations:
  • When the PBX acts as a server, a server certificate is required.

    If the PBX requires to verify TLS client (PBX Settings > SIP Settings > TLS > TLS Verify Client), you need to upload a client certificate to both PBX and TLS client, or the TLS connection would fail.

  • When the PBX acts as a client, whether a client certificate is required depends on the server.

    If the PBX requires to verify TLS server (PBX Settings > SIP Settings > TLS > TLS Verify Server), you need to upload a server certificate.
