For G.729B CODECs, use this option to enable or disable silence compression. When enabled and silence
is detected, RTP (i.e., digitized voice) data is not sent as part of the data stream. This conserves
bandwidth. When disabled, RTP data is always sent as port of the data stream, even if there is no actual
digitized speech. Silence compression uses the following modules:
- VAD (Voice Activity Detection
- DTX (Discontinuous Transmission)
- SID (Silence Insertion Descriptor)
- CNG (Comfort Noise Generator)
DSX IP Keysets support G.729B silent compression, although some third-party SIP SLTs may not.
