Voice Solutions


Our range of highly resilient and competitive Wholesale voice services include:



Carrier interconnect

The choice for carriers wishing to perform a bi-lateral interconnect with the Vocus Voice Network using our preferred SIP Standard. 

Carrier Voice Connect (CVC)

Whether you’re looking for local call termination or global hand-offs, we have the reach to support you. We interconnect through all Australian and New Zealand carriers, along with dozens of international interconnection partners. With competitive rates and best-in-class call quality, CVC is available via SIP using Vocus access products for connectivity.

Inbound Service

As a Tier 1 voice provider, we deliver domestic toll-free inbound number services across New Zealand. 

Number Allocation

We can provide individual or number ranges from most local areas across New Zealand. Calls to these numbers are delivered to your existing Vocus point of interconnect, whether it's local to the zone of origin or backhauled to your point of interconnect in remote zones. 

Number Portability

Easily migrate your clients' numbers from your competitors' infrastructure to your own. Calls to ported numbers are delivered to your existing Vocus point of interconnect. In addition to geographic DDI numbers, Vocus can port in toll-free and local rate numbers. 

SIP Trunks

With more than 1 billion minutes of voice calls handled across our network last year, we have the capability and scale to deliver high-quality connections for resale, coupled with value-added services including number ranges, porting, and inbound numbers. 

International Customers

If you don't have a New Zealand point of presence, we can connect to you using public IP and can provide all voice services, plus specialised call termination for international customers. 

Why choose Vocus?
