Like every SmartNode™, the SN4400 supports every industry-standard CODEC to deliver toll-quality voice on every call.

Patton’s DownStreamQoS™ delivers the advantage of clear, uninterrupted voice-and-data communication. In addition, SmartNode delivers a smooth transition to VoIP with strong number portability support accepting incoming calls from the PSTN throughout the VoIP service provider's number porting process.
