Why Spark PSTN Interconnect?

Spark PSTN Interconnect provides you a basic, yet highly reliable calling service that you can ‘dress’ with your own voice services to meet your customer needs.

We own the largest copper network in New Zealand, making our service a smart choice for providers wanting a low-cost option to terminate calls to any Spark or RSP customer in the country.

What’s more, we maintain interconnect agreements with other major telecommunication providers and through our scale and buying power, we are able to pass discounted calling costs directly on to you.

Key features

  • Connects to Spark’s PSTN
  • Enables fixed and mobile services
  • Lowest cost option to terminate to Spark customers
  • Enables termination to any RSP in New Zealand

How it works

To interconnect with our network, your network needs to be compatible with our PSTN. This means your network equipment will need to use the ITU G703 transmission standard and CCS7 signalling protocol.

Independent testing of your equipment will be required to confirm that it complies with the Permit to Connect (PTC) standards established.  This will ensure networks work properly together and provide a satisfactory service to you and our end users.

More information on the PTC process can be found HERE

Each PSTN Interconnect service agreement is negotiated individually. Our standard reference offer can be found HERE
