will cause the OBi to interleave the ring signal applied to
each port to reduce the chance of overloading the power
supply.
Note: Option available only on OBi202/OBi302

Out of band DTMF tone playback level in dBm (-90 to 3)
Caller ID delivery standard. Choices are:
FSK(Bell202)
FSK(V.23)
DTMF(Finland,Sweden)
DTMF(Denmark)
Triggering event for on-hook Caller ID signal generation.
Choices are:
After First Ring
After Polarity Reversal
Before First Ring
Transmit gain in dB (-12 to 12) to apply to signal sent from
OBi to the attached phone(s)
Receive gain in dB (-12 to 12) to apply to signal received
by OBi from the attached phone(s)
PHONE port silence detection servers the purpose of
driving silence suppression in RTP transmission when the
phone Call terminates on SP1/2 or OBiTALK Service and
silence suppression is enabled.
This parameter is used to set a sensitivity level for OBi
silence detection algorithm. Available choices are:
Low (harder to detect silence)
Medium (suggested)
High (easier to detect silence)
