11. Phone Setting
11.1 Master Setting
*
Master Number
: The number that FXO dial out (i.e. the phone number of F in
the system topology). System uses this number to authenticate the caller ID
of PSTN incoming call. If the caller ID matches to the setting in the master
number, it has the permission to dial out via GSM in MV (i.e. F-D-B-G or
F-D-B-H).If the matching result is failed, the PSTN incoming call will ring the
local FXS directly (F-D-C).
*
No Answer Fwd Time Out
: Setup the FXS ringing period. For VOIP call
from MV, system always rings local FXS first. After ringing period, system
change to dial master number via FXO port. (Parameter “0”: forwarding to
PSTN directly.)
