Setting CO Line Extension Number
An extension number in InterPBX Communication System might represent a
CO line, an analog extension, an IP extension, a CO line group or an extension
group.
In “Extension Number” it will display the extension number of this CO Line
port automatically based on your settings under “CO Line Extension Base”, you
may also change the extension number from here. Please select “Enabled” to
activate this port. For maintenance purpose, you may click again on “Enabled”
to disable this port. In “Description” input the telephone number or other
information for this port.
CODEC
Choose the preferred CODEC from PCM, G.723.1 or G.729 supported by
InterPBX Communication System. PCM CODEC compresses and decompresses
voice conversation to 64 Kbps providing the best speech quality but consumes
larger bandwidths. G.723.1 CODEC uses 5.3/6.3 Kbps, the less bandwidth from
the three choices but may result in poorer call quality and finally G.729, which
uses 8 Kbps.
Setting Fax Ext Number
InterPBX Communication System can detect the fax signal from the CO Line.
Please enter the extension number of your CO Line port that connected to your
Fax machine. When there is an incoming fax, the fax will be automatically
transferred to the extension’s connected fax machine.
