Solutions for Business Needs Voice Over IP

Increasingly, businesses need a security strategy for streaming voice and video applications  that converge with existing data applications on the same networks, such as  teleconferencing,  digital voicemail and Voice Over IP (VoIP). Easily managed and highly cost-effective, Dell SonicWALL® Converged Network Security solutions offer high-performance, multi-layered security, while maintaining Quality of Service (QoS) for time-sensitive voice and video applications.

Access to remote converged networks.

Offering integrated IPSec and SSL VPN technologies on select models, Dell SonicWALL VoIP Firewalls deliver access to vital business resources for employees, distributed office sites, partners and contractors from anywhere. Moreover, you can easily configure VoIP traffic between third-party VoIP telephony devices to traverse any Dell SonicWALL Secure Remote Access (SRA) solution.

Control over optimal QoS.

A lack of VoIP bandwidth can drop communications and reduce productivity. Dell SonicWALL VoIP Firewalls deliver built-in QoS bandwidth optimization, featuring support for VoIP-ready H.323 and SIP, as well as full VoIP over Wireless LAN (WLAN). Dell SonicWALL Application Intelligence can extend beyond QoS to dedicate bandwidth for VoIP traffic or restrict bandwidth for non–VoIP traffic. To ease management, Dell SonicWALL Management and Reporting solutions offer real-time monitoring and alerts, as well as intuitive compliance and usage reports, all from a single management interface.

Security against threats for all VoIP traffic.

Converged networks not only require the same security as other networks, but also demand high performance to maintain quality of service. Dell SonicWALL VoIP Firewalls combine high-speed Reassembly-Free Deep Packet Inspection™ (RFDPI) with robust, multi-layered Unified Threat Management (UTM) security services to protect the converged network, as well as all VoIP traffic between VoIP telephony devices, from the latest threats and vulnerabilities in real time. Dell SonicWALL UTM employs expanding array of seamlessly integrated services featuring gateway anti-virus, anti-spyware, comprehensive anti-spam, intrusion prevention, enforced desktop anti-virus, content filtering, and Application Intelligence.

Assured retention of crucial voicemail.

Dell SonicWALL Continuous Data Protection (CDP) solutions offer flexible Offsite Data Backup, Site-to-Site Data Backup, Local Archiving and Bare Metal Recovery options to address any unexpected disruptions in access to VoIP systems and data —even if the original device platform is unavailable.
