MP-500 MSBG
Parameter Description
Notes:
Typically, the Caller ID signals are generated/detected
between the first and second rings. However, sometimes
the Caller ID is detected before the first ring signal (in such
a scenario, configure RingsBeforeCallerID to 0).
Caller ID detection for Britain [4] is not supported on the
device's FXO ports. Only FXS ports can generate the
Britain [4] Caller ID.
To select the Bellcore Caller ID sub standard, use the
parameter BellcoreCallerIDTypeOneSubStandard. To
select the ETSI Caller ID substandard, use the parameter
ETSICallerIDTypeOneSubStandard.
To select the Bellcore MWI sub standard, use the
parameter BellcoreVMWITypeOneStandard. To select the
ETSI MWI sub standard, use the parameter
ETSIVMWITypeOneStandard.
If you define Caller ID Type as NTT [2], you need to define
the NTT DID signaling form (FSK or DTMF) using
NTTDIDSignallingForm.
