Parameter Description
✔ FXO Interfaces: For IP-to-Tel calls:
1) Upon incoming INVITE message, the FXO
interface goes off-hook (seizes the line).
2) Upon detection of a Wink signal from the Tel
side (instead of a dial tone), the device dials the
digits, "KP911ST" (denotes *911#).
3) The device waits for polarity reversal change
from normal to reverse for an interval of 2,000
msec.
4) Upon detection of a polarity reversal change, the
device dials the DTMF (or MF) digits of the calling
party (number that dialed 911) in the format
"KP<ANI>ST" (*ANI#), where ANI is the calling
number from the INVITE. If no polarity reversal, the
FXO goes idle.
For example: (Wink) KP911ST (Polarity Change)
KP02963700ST
Note: The Enable911PSAP parameter must be set
to 1.
Note:
■ For FXS interfaces, the EnableReversalPolarity and
PolarityReversalType parameters must be configured
to 1.
■ The parameter is applicable to FXS and FXO
interfaces.
■ The corresponding global parameter is
EnableDIDWink.
'Enable 911 PSAP'
enable-911-psap
[TelProfile_Enable911PSAP]
Enables the support for the E911 DID protocol, according
to the Bellcore GR-350-CORE standard. The protocol
defines signaling between E911 Tandem Switches and the
PSAP, using analog loop-start lines. The device's FXO
interface can be used instead of an E911 switch,
connected directly to PSAP DID loop-start lines.
■ [0] Disable (default)
■ [1] Enable
Note:
■ The parameter is applicable only to FXO interfaces.
■ The corresponding global parameter is
Enable911PSAP.
IP Settings
'Coders Group'
coders-group
[TelProfile_CodersGroupName]
Assigns a Coder Group, which defines audio (voice) coders
that can be used for the endpoints associated with the Tel
Profile.
To configure Coders Groups, see Configuring Coder
Groups.
'RTP IP DiffServ'
rtp-ip-diffserv
Defines the DiffServ value for Premium Media class of
service (CoS) content.
