Voice Services
Juniper Networks helps service providers ensure their IP Infrastructure can efficiently deliver VoIP services to customers including:
- Proper prioritization of VoIP traffic in conjunction with other network traffic, to ensure appropriate quality.
- Network resiliency to keep calls connected, even during unexpected network events.
- VoIP session awareness - the intelligence to handle calls appropriately.
- VoIP security to protection against attacks and against service compromise and abuse.
- Secure and intelligent connection of VoIP peering networks
Working closely with our strategic partners, Juniper Networks provides a complete, standards-based solution for the delivery of VoIP services.
Overview
Support for VoIP requires a network that is intelligent enough to prioritize traffic types and resilient enough to prevent dropped calls. Juniper Networks M-, MX-, and T-series routing platforms integrate Session Border Control to prioritize VoIP traffic appropriately. The Juniper integrated SBC is standards-based, enabling third parties to quickly integrate their solution for an end–to-end VoIP network. In addition, Juniper Networks router platforms include the latest in ASIC technology, a full MPLS feature set, and enhanced QoS technology — all running on one JUNOS operating system for maximum operational efficiency.
VoIP also presents unique security challenges. Providers must protect not only the VoIP media, but also the VoIP signaling, since both can be targets for attack. Inadequate security can lead to denial of service as well as unauthorized access to VoIP systems and other security breaches. Security devices must handle the small-packet characteristics of VoIP traffic to maintain call quality end-to-end. Juniper Networks Firewall/IPSec VPN and Intrusion Detection and Prevention (IDP) appliances defend VoIP networks from security threats, readily handling the unique processing demands of VoIP traffic at the scale required by provider networks.
