Telefónica International Wholesale Deploys Acme Packet

Telefónica International Wholesale Services is deploying Acme Packet's Net-Net session border controllers to deliver its business voice-over-IP (VoIP) trunking services. Telefonica Wholesale manages all of Group Telefonica's voice, IP, data and capacity wholesale services worldwide. Its network extends more than 45,000 km across Europe, Latin America and the United States, providing access to 150 international voice carriers.

Telefonica Wholesale's VoIP services enable its carrier customers to trunk business voice traffic originating from enterprises or carrier circuit switches to optimum PSTN termination points-of-presence around the world. The enterprise voice traffic may be sourced from traditional TDM-based PBXs or IP PBX using H.323 or SIP. The services are commercially available this quarter - Q4, 2005.

Telefónica International Wholesale is using Acme Packet's Net-Net session border controllers to interconnect (peer) with its carrier customers. The equipment supports security functions including access control, network topology hiding and DoS protection against both signaling and media attacks and overloads. The admission control, QoS marking/mapping and QoS reporting features are imperative for compliance with both carrier and enterprise Service Level Agreements. To maximize service reach, the session border controllers mediate between private overlapping IP address spaces and dialing plans, providing basic, but critical, connectivity to both Telefonica Wholesale's customer carrier networks and their connected enterprises. Lastly, the Net-Net session border controllers are responsible for optimized, least-cost routing of VoIP traffic.

  • In April 2005, Acme Packet announced that Telefónica de España had selected its Net-Net session border controllers for its hosted business and residential VoIP offering throughout Spain.
