Our SIP Lines can register over NBN or an internet connection. However, for guaranteed voice quality we recommend provisioning the SIP Lines over Prosum’s secure **access tail. We are more than happy meeting with you and discussing a solution that suits your requirements.
**Managed Cisco router is required for private access tail.
