SIP Connect for Resellers

Enable your enterprise customers to converge their voice and data networks and build a pathway to unified communications


Telstra SIP Connect is our global SIP Trunking solution to replace traditional ISDN lines between on-site phone and unifi­ed communications. And the connectivity is delivered via Telstra’s global network through broadband ethernet only, by access options of using IPVPN, public internet or internet IPSEC where regulatory permits. All of your enterprise customers’ national and global voice and data offerings can be packaged onto one IP connection to the outside world.

  • IP VPN - SIP Trunking via IPVPN across two Network Node Interfaces (NNI) as primary and secondary backup solution.  Telstra offers two NNIs at a data rate based on the enterprise end-customer’s service requirements. A 100mb connection accommodates approximately 1000 channels.  The bandwidth can be increased dependent on service requirements to 1GE and 10GE respectively.
  • Public Internet - SIP trunking interconnect via the Public Internet with SIP signalling and Media (RTP) directed from the Customer Edge/border element at enterprise customer’s premises towards the public Internet interface of the Telstra platform.
  • Internet IPSEC - This Public Internet connectivity option ensures the voice activity is encrypted. In this architecture, the Telstra reseller connects their sites to Telstra via the public Internet with SIP signalling directed from the Customer Edge/border element at the customer’s premises towards the Telstra Gateway, and then onwards towards Telstra’s platform via MPLS. The Media (RTP) is directed from the Customer Edge/border element at enterprise customer’s premises towards the public Internet interface of the Telstra SBC.

With Telstra SIP Connect, your customers can enjoy access to in-country and international PSTN numbers and calling at competitive rates. Telstra provides one central SIP Trunking connection into our IPVPN, which you can deliver to customers. You can white-label any number of on-demand, low-cost, high-quality SIP Trunking solutions to support your customers’ voice and data communications.
