SIP Trunking Provider Network Over a Managed Line Over the Public Internet PSTN Public Internet SIP Trunking Provider Network GW SIP System Data & VoIP LAN IP- PBX SIP Trunk over Internet Firewall PSTN SIP Trunking Provider Network GW Public Internet SIP System Managed SIP Trunk Firewall IP- PBX There are two ways to connect to a service provider, both of which are reliable and safe. Many service providers, especially larger ones, offer connections over “managed lines”. The benefit of course is that the service provider can control the Quality of Service delivered over that connection and will offer Service Level Agreements (SLAs) to their customers. The downside of this approach is that it is more expensive and may not allow the end user the freedom to converge all networks into one. This solution may also leave the end customer vulnerable to security risks. The second method is receiving the SIP Trunks over the Public Internet.This is usually a less expensive option and usually results in a truly converged internal network where all of the voice and data services reside on the same LAN. Of course, with this model the customer has to solve the NAT traversal issue to get through the firewall and all of the security risks that are of concern for any connection to the Internet are equally if not more important to a VoIP installation, because the IP-PBX could be exposed to attack. Since communications is highly important, perhaps critical for most businesses, there should be no tolerance for exposing the IP-PBX to the Internet without protecting it with an Enterprise Session Border Controller.

Why does the Enterprise need an SBC? Eliminate interoperability issues Resolve NAT traversal through the firewall Security Place the PBX in the private IP space Authenticate to prevent theft of services Protect against Denial of Service attacks Eliminate single points of failure Manage bandwidth for optimal voice experience Measure quality of the voice Encryption of Signaling and Media for privacy
