To connect your phone to stg-servisai-teststaging.kinsta.cloud, you must use either Twilio, RingCentral, or Netlink. Admin users should navigate to this link https://freeagent.network/settings/voip to enable VoIP calling. Then, they can choose Twilio or RingCentral for the connection, which means you must have a license with one of those providers.
