Notes:
•
Profile 1: G.711 at 20ms only, with In-band signaling (in voice channel), DTMF
transcoding (RFC 2833 to in-band signaling), and Silence Suppression (no fax
detection or T.38 support).
•
Profile 2: G.711, G.726, G.729, G.723.1, AMR-NB, T.38 with fax detection, In-band
signaling (in voice channel), and Silence Compression.
•
Acoustic Echo Suppressor reduces performance by about 30%. For more
information, contact your AudioCodes sales representative.
•
MPMB is the optional, Media Processing Module that provides additional DSPs,
allowing greater capacity.
The device can handle up to 5,000 fax detections, answer detections (AD), answering
machine detections (AMD), beep detections, and Call Progress Tone detections, with the
following assumptions:

Timeout for fax detection is 10 seconds (default), after which fax detection is turned off
and the call is resumed without the fax detector.

Fax detection is applied on both legs of the SBC call.

Minimum call duration is 100 seconds.

AD, AMD, beep detection, and Call Progress Tone detection is only on one leg of the
SBC call (should this not be the case, capacity figures will be reduced)
