Explaining the Embedded Common Audio Transcoding Feature of SBCSE2600

The Embedded common audio transcoding enables the SE2600 to convert media packets from one media format to another. With this feature, the SE2600 allows UEs using different media formats to communicate with each other.

This feature supports the following types of media format conversion:

• Conversion between G.711 (including G.711 a-law and G.711 μ-law) audio signals, G.729 (including G.729A and G.729AB) audio signals, and adaptive multirate (AMR) audio signals, between G.711 a-law audio signals and G.711 μ-law audio signals, between same G.711, G.729, or AMR codec formats with different ptime values, and between different G.711, G.729, or AMR codec formats with different ptime values.
• 
  
• Conversion between fax over T.38 and fax over G.711.
• 
  
• Conversion between G.711 dual tone multiple frequency (DTMF) and RFC 2833 DTMF, between G.711 DTMF (on the bearer plane) and SIP INFO DTMF (on the signaling plane), and between RFC 2833 DTMF (on the bearer plane) and SIP INFO DTMF (on the signaling plane). SIP is the abbreviation of Session Initiation Protocol.

Benefits of this feature to carriers:

Benefits to Subscribers:

This feature enables subscribers using different media formats to call each other.

Requirements

Involved NEs :
