Version 7.2 597 Mediant 1000B Gateway & E-SBC
User's Manual 27. Configuring Supplementary Services
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.

Digits of Calling
Number (ANI)
Digits of Displayed Number Number Dialed MF Digits
8
"nnnnnnnn"
- MF dialed "KPnnnnnnnnST"
12
"nnnnnnnnnnnn"
None "KPnnnnnnnnnnnnSTP"
12
"nnnnnnnnnnnn"
10
"mmmmmmmmmm" (pANI)
"KPnnnnnnnnnnnnSTKPmmmmmmmmmmST"
2
"nn"
None "KPnnSTP"
1
"n"
- MF dialed "KPnST"
For example:
"From: <sip:8>@xyz.com>" generates device
MF spill of KP 8 ST
