SIP User's Manual
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:
♦
♦
♦

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:
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.

Table notes:

For all other cases, a SIP 484 response is sent.

RxDTMFOption = 3
TxDTMFOption = 4
RFC2833PayloadType = 101
If the two-wire cable is crossed, the SetDefaultLinePolarityState parameter
must be set to 1.
