Wholesale SIP Trunks

Wholesale SIP Trunks deliver raw Voice over IP connectivity with multiple Direct Dial-In (DDI) numbers and scalable channels, giving IT teams and virtual ISPs full control over their telephony infrastructure. It’s a cost-effective and predictable way to handle large volumes of calls without the need for traditional phone lines or hardware. Whether you’re running your own PBX, hosted system, or cloud telephony platform, SIP Trunks provide flexible, reliable voice paths that can grow with your business or service offering.


Technically, our SIP Trunks support high availability with redundant routes, secure SIP signaling with TLS and SRTP encryption, and number porting for seamless migration. We offer flexible channel counts, allowing you to add or reduce capacity as needed, and full support for emergency calling compliance. Plus, you get local NZ DIDs, caller ID management, and detailed call logging for easier billing and troubleshooting. Delivered over CloudLink’s robust fibre and wireless networks, it’s voice connectivity built for performance, security, and scale.
