7 Fax Transcoding Support for the Acme Packet 1100

When equipped with the Foreign Exchange Office-Foreign Exchange Subscriber (FXO-FXS) interface and a transcoding Digital Signal Processor (DSP), the Acme Packet 1100 can transcode analog fax calls into the T.38 codec for better transmission quality. When the DSP detects Fax tones, it triggers the Oracle® Enterprise Session Border Controller (ESBC) to ask the Fax gateway to switch to the T.38 codec. You must configure the ESBC, by way of codec policies, local policies, and realm configurations, to accept the T.38 codec and let the DSP detect the fax tone to trigger the codec negotiation.

For more information about transcoding, see the ACLI Configuration Guide.
