Voice over IP (VoIP)
Inband
The PBX uses the same channel to transfer the DTMF signals and the voice
data (DTMF tones).
Outband (RFC 2833)
The PBX uses different channels to transfer the DTMF signals and the voice
data. The DTMF tones are filtered out of the voice data.
Both procedures
The PBX transmits the DTMF signals on two channels (1st contains DTMF
tones together with the voice data + 2nd contains the DTMF signal).
Echo Cancellation
This compensates for local echoes and reverberation effects.
Jitter buffer (40 to 160)
The size of the jitter buffer specifies how many RTP packets can be cached,
to buffer disruptions or compensate for them.
Codec settings
Requirements:
•
external VoIP channel that supports different codecs (optional, see
Technical Data in the Instructions)
•
VoIP provider who supports the different codecs
