for a Hosted PBX / IP Centrex Environment
Hosted PBX / IP Centrex services provide a valuable potential source of new revenue for IP service providers wishing to attract and retain customers. These services offer businesses a number of advantages over traditional Centrex phone systems, including lower initial investment costs, reduced rates for interoffice/toll calling, easier moves/adds/changes, greater portability for branch office and remote workers, and more sophisticated call routing and messaging capabilities.
However, customer network problems—such as congestion, misconfigured routing, or equipment failure—can cause severe call quality degradation. The service provider will often be blamed for the poor service levels, even when the problem originates on the customer LAN. Because there is typically a firewall router between the customer and service provider, it can be difficult or impossible for Hosted PBX / IP Centrex providers to diagnose and resolve quality problems without a truck roll to the customer site.
Telchemy's performance management framework is designed to overcome these difficulties, providing real-time performance metrics and diagnostic data directly from the customer premises even in the presence of a firewall. Telchemy is the first company to offer support for RFC 6035, the industry's preferred SIP-based VoIP performance reporting protocol.
