Requirements:
•
Subscriber is a VoIP end device
Jitter buffer
Specifies the size of the jitter buffer in milliseconds (duration of the audio
signals). In this time period RTP packets are cached (lower values = lower
number, greater values = greater number). Delays in the transmission and
loss of packets can be compensated that way.
Echo cancellation
The system compensates for local echoes and reverberation effects
during internal VoIP calls.
Format of transferred phone number
The PBX supports several formats to display the country code of incoming
calls on the display of the VoIP phone being called, e. g. adjusted to a small
display.
Note:
For some phones of other manufacturers it may be necessary to
select the option
Without country code (e.g. 05306...)
so that the
country code is dialled with a zero when calling back. This configuration
is not necessary for system phones.
