Module-Update from which URLs / IPs

General Help
1

Hi all,

I want to secure my FreePBX-System by only allowing connections to and from known IPs (SIP-Provider, Telephones and systemrelevat IPs).

From which URLs (or better IPs) FreePBX gets its Updates?:

  • Module-Update by Module-Admin
  • System-Updates by System Admin Pro Module

Are there any other connections required back to Sangoma or FreePBX (e.g. for System Activation, Registration of Modules/Deployments).

Would appreciate any list of used URLs/IPs.

Thanks and best regards,
Patrick
