Application—Edge intelligence of enterprise communication

Enterprises are excited about voice over IP and convergence for the following reasons:

•Bypassing the PSTN. Using Internet telephony service providers (ITSPs) instead of incumbent carriers dra- matically reduces telephony costs

•IP PBXs, with their full suite of features and ease of integration into existing IT environments are very appealing

•Convergence lowers technology ownership costs and enables enterprises to deploy new integrated applications

However, there are several concerns about migrating the whole telephony infrastructure to VoIP:

•Loss of voice quality

•Unknown reliability

•Lack of experience/expertise in voice over IP

Patton’s SmartNode series of VoIP gateways address these concerns enabling enterprises to safely migrate to VoIP. SmartNodes enable system administrators to gradually introduce VoIP, using it as the edge communica- tion device for all worlds, connecting PSTN, legacy PBX, ITSPs and an IP PBX.
