les deux procédés
The PBX transmits the DTMF signals on two channels (1st contains DTMF
tones together with the voice data + 2nd contains the DTMF signal).
Compensation de l’écho
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.
Paramètres Codec
Requirements:
• external VoIP channel that supports different codecs (optional, see
Technical Data in the Instructions)
• VoIP provider who supports the different codecs
The PBX makes various codecs available. The selection of a codec affects
the quality of a VoIP call. Different codecs can be configured, depending
on the available connection bandwidth, ranging from codecs with the best
possible VoIP call quality down to codecs with high compression (low
bandwidth). The codec actually used for a call is not fixed until the codec
is negotiated with the VoIP provider.
Meilleure qualité possible
Selects a codec sequence with best possible VoIP call quality (high
bandwidth) as highest priority.
