You left out the part where you described

  - the certificates you have for each computer
    - whether they are valid under normal pkix validation rules
    - if not, how you configured custom trust anchors
  - how you are installing certificates and keys for linphone to use
  - how you configured linphone to listen on tls/5061

  - what kind of certificate and key management doctrine allows users to
    have access to system certificates
