VoIP/SIP Convergence is designed for two key deployment scenarios: as a branch SBC, or as a centralized SBC for enterprise applications.
 

SBC Branch
In the branch application, the SBC provides the secure link between the Internet or enterprise WAN connection and the branch office switching system and associated IP telephones. The SBC provides multiple functions for this configuration, including data routing, firewall, SIP NAT handling, QoS and traffic shaping, call admission control, VoIP security, and call routing via a SIP Proxy.
 

Centralized SBC
In the enterprise application, the SBC provides the link between the Internet or enterprise WAN connection and a SIP-based softswitch. The SBC protects that softswitch from unauthorized access, and also provides topology hiding, Layer 7 packet inspection for firewall pinhole functions, QoS and traffic shaping, and NAT handling. The enterprise and branch scenarios can be combined, thus providing a controlled, secure link between the branch office switching system and the centralized softswitch.

Why an end user wants to take on Open Source VoIP/SIP Convergence solutions from a Wireless Reseller
Deploying a secure Open Source communications network in multi-site environments requires the implementation of voice enabled high speed convergence gateways, security switching & VoIP/SIP routing, wireless switching, mobility gateways, FMC gateways, QoS, and security of all network layers (IP Transport/Packet Handling Layer, Policy and Control Layer and Application & Service Layer) to ensure voice quality and protect from the vast and constantly changing network attacks that customers are facing daily from both inside and outside of the network.

Security is currently focused primarily on data. VoIP/SIP communications networks need to support mixed traffic and provide transport layer security and will require this single layer focus to be significantly expanded to a complex, multi-layer solution including the need to secure the media, control and signaling layers and service/application layer security, and the endpoint device over the wireless deployment.

With IP communications there isn’t any longer a concept of a simple network. Wireless reseller partners must take particular pains to ensure that they provide their customers with a secure solid “5-nines” quality enabled communications network infrastructure. Customers look to experienced Wireless reseller partners that are highly customer facing with experience to identify their business challenges and provide a secure network infrastructure for data & communications solutions is an important differentiator.
