VoIP Basic Configuration to H.323 protocol
VoIP Basic Configuration: (Configure the VoIP protocol to H.323 Protocol)
Configure the numbering with FXS / FXO ports. (Depending on model)
FXS Number:
The representation number is the phone number of the telephone that is connected to FXS
port.
FXO Number:
FXO ports are connected to the extension ports of the PBX system or the PSTN line. They
have a common Line Hunting Group Number. When this number is dialed, the Gateway system
will find a free FXO line connected to PBX. This hunting will skip all busy lines and absent lines
and find only the idle line to the PBX. After the available line is found, you can hear the dial tone
from PBX. After that, you can dial the needed phone number out through PBX.
Configure the ANI (Answer Number Indication) / Caller ID of the FXS/FXO ports.
ITSP needs ANI for authorization when gateway calls Off-Net call to PSTN number or mobile phone
number.
