Mediant 500 MSBR
detected by the device and forwarded to the IP, using RFC 2833 telephony events (or
inband, depending on the device's configuration). Typically, this Wink signal followed
by the DTMF digits initiates a call transfer.
For supporting the E911 service, used the following configuration parameter settings:

Enable911PSAP = 1 (also forces the EnableDIDWink and EnableReversalPolarity)

HookFlashOption = 1 (generates the SIP INFO hookflash message) or 4 for RFC 2833
telephony event

WinkTime = 700 (defines detection window of 50 to 750 msec for detection of both
winks - 250 msec wink sent by the PSAP for starting the device's dialing; 500 msec
wink during the call)

IsTwoStageDial = 0

EnableHold = 0

EnableTransfer = 0
•
Use RFC 2833 DTMF relay:
♦
RxDTMFOption = 3
♦
FirstTxDTMFOption = 4
♦
RFC2833PayloadType = 101

TimeToSampleAnalogLineVoltage = 100

WaitForDialTime = 1000 (default is 1 sec)

SetDefaultLinePolarityState = 0 (you need to verify that the RJ-11 two-wire cable is
connected without crossing, Tip to Tip, Ring to Ring. Typically, the Tip line is positive
compared to the Ring line.)
Note: If the two-wire cable is crossed, the SetDefaultLinePolarityState parameter
must be set to 1.
The device expects to receive the ANI number in the From and/or P-Asserted-Identity SIP
header. If the pseudo-ANI number exists, it should be sent as the display name in these
headers.
