NetBorder Transcoding Gateway

 

Product Overview 

The NetBorder Transcoding Gateway is an IP to IP VoIP transcoding and media server.  It operates as an intelligent SIP back to back user agent to provide any to any audio codec transcoding and media processing while allowing business logic to remain in the Soft Switch.

Here is a high level list of the functions that could be performed by this product to fix the various media incompatibilities that could be found by two VoIP endpoints.

• Any to Any voice codec conversion (ex: G729, G722, G711...) 
• RTP packet size conversion
• RTP DTMF event (RFC4733) to/from inband DTMF
• Noise Reduction *
• Voice Quality Enhancement *
