vAD
Voice Activity Detection (speech detection) is a technique used in speech processing
wherein the presence or absence of human speech is detected in regions of audio. In
VoIP applications, the main use of VAD is to avoid unnecessary coding and transmission
of silence packets, saving on computation and on network bandwidth.

DtMF
DTMF (Dual-tone multi-frequency) signalling is used for telephone signalling over the
line to the phone switch or PBX.
If the device itself generates the tones and it is sent in the voice-frequency band, the
method is called Inband. Using VoIP, this is not the best method. Low bit rate codecs
may corrupt the signalling tones and make them hard to recognize for the switch.
RFC 2833 is a method for carrying DTMF-signalling in RTP packets using a separate
RTP payload format. With this method a PSTN gateway reproduces the DTMF tones
sent from the end device.
With SIP Info the DTMF signalling is sent as SIP requests. The SIP switch creates the
tones if the call is transferred to the PSTN.
Use RFC 2833 or SIP Info as preferred methods. Switch to inband only if you encounter
problems using DTMF signalling with your PBX/SIP switch.
