Vocoder Type Drop Down Menu
The Vocoder Type drop down menu, shown in Figure 95, indicates the bit rate at which audio is converted into digital format.
This feature is used to configure communication between the IP-223 and C-Soft.
Available selections for this field are: ADPCM (Adaptive Differential Pulse Code Modulation) 16K and ADPCM 32K.
NOTE: Design considerations must take into account that although 16K uses less bandwidth, the audio quality might not
perform as desired.
IMPORTANT: Vocoder configurations must be the same across devices and C-Soft.
Enable Check Box
The Enable check box is used to setup a phone ring when phone calls are received. The entry for a ring signal must be a
unique Multicast Address and different from the other lines.
Line Name Field
The Line Name field is used to enter an alphanumeric label for the phone ring setup.
This field can contain up to 12 characters.
Multicast Address Field
The Multicast Address field is used to enter the multicast address for the ring. This number must be between 224.0.0.2 and
239.255.255.255. The console must be setup with the same multicast address in order to hear the phone ring.
