Converged communication&nbsp;networks widen the attack surface for malicious&nbsp;players on the Internet. IP telephony opens the&nbsp;enterprise network to such vulnerabilities as toll&nbsp;fraud, denial of service (DoS) and distributed denial&nbsp;of service (DDoS) attacks, among others.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With toll fraud, the company may never notice the intrusion until the exorbitant phone bill comes in. With DoS\/DDoS the loss of network resources is quickly apparent, yet the disruption of business operations is costly, and may take hours or days to resolve.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>We propose an enterprise network security solution for SIP (session initiation protocol) based VoIP telephony with SIP trunking service delivered by an Internet telephony service provider (ITSP).<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The proposed solution relies on an enterprise session border controller (eSBC) installed as customer premise equipment (CPE) at the subscriber location.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For details about this solution get the new Patton White Paper: &gt;&gt;<a href=\"https:\/\/www.patton.com\/netprotection\">Secure All-IP Telephony<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Network protection is serious business.
