local and toll-free over traditional trunking
methods
o IP Flex enabled porting of local and 800 #s into
primary Data Center

We strongly recommend use of SBC for ALL SIP Trunk Deployments
Session Border Controller – “Firewall for SIP / VoIP”
Secure the borders of a VoIP network
Protect VoIP, video and UC sessions
Authentication, Encryption, NAT traversal, DoS protection
Fix protocol interworking issues
Assure & measure session quality
Monitoring, reporting, & troubleshooting (demarc)
Traditional firewalls cannot:
Prevent SIP-specific overload conditions and malicious attacks
Open / close RTP media ports in sync with SIP signaling
Track session state and provide uninterrupted service
Perform interworking or security on encrypted sessions
Scale to handle many 1000s of real-time sessions
Provide carrier class availability
