Version 7.2 1083 Mediant 1000B Gateway & E-SBC
User's Manual 65. Configuration Parameters Reference
Parameter Description
622125519100 Ext. 104, the device receives the SIP INVITE (from
Microsoft's application) with the URI user part as INVITE
sip:622125519100;ext=104@10.1.1.10 (or INVITE
tel:622125519100;ext=104). If the parameter EnableMicrosofExt is
enabled, the device modifies the called number by adding an "e" as
the prefix, removing the "ext=" parameter, and adding the extension
number as the suffix (e.g., e622125519100104). Once modified, the
device can then manipulate the number further, using the Number
Manipulation tables to leave only the last 3 digits (for example) for
sending to a PBX.

sip-uri-for-
diversion-header
[UseSIPURIForDiversionHe
ader]
Defines the URI format in the SIP Diversion header.
 [0] = 'tel:' (default)
 [1] = 'sip:'

100-to-18x-timeout
[TimeoutBetween100And18
x]
Defines the timeout (in msec) between receiving a 100 Trying
response and a subsequent 18x response. If a 18x response is not
received within this timeout period, the call is disconnected.
The valid range is 0 to 180,000 (i.e., 3 minutes). The default is 32000
(i.e., 32 sec).

definition settings >
immediate-trying
[EnableImmediateTrying]
Determines if and when the device sends a 100 Trying in response to
an incoming INVITE request.
 [0] = 100 Trying response is sent upon receipt of a Proceeding
message from the PSTN.
 [1] = (Default) 100 Trying response is sent immediately upon
receipt of INVITE request.
configure voip > sip-
definition settings > trans-
coder-present
[TransparentCoderPresentat
ion]
Determines the format of the Transparent coder representation in the
SDP.
 [0] = clearmode (default)
 [1] = X-CCD
configure voip > sip-
definition settings >
ignore-remote-sdp-mki
[IgnoreRemoteSDPMKI]
Determines whether the device ignores the Master Key Identifier
(MKI) if present in the SDP received from the remote side.
 [0] Disable (default)
 [1] Enable
Comfort Noise Generation
Negotiation
configure voip > media rtp-
rtcp > com-noise-gen-nego
[ComfortNoiseNegotiation]
Enables negotiation and usage of Comfort Noise (CN) for Gateway
calls.
 [0] Disable
 [1] Enable (default)
The use of CN is indicated by including a payload type for CN on the
media description line of the SDP. The device can use CN with a
codec whose RTP time stamp clock rate is 8,000 Hz (G.711/G.726).
The static payload type 13 is used. The use of CN is negotiated
between sides. Therefore, if the remote side doesn't support CN, it is
not used. Regardless of the device's settings, it always attempts to
adapt to the remote SIP UA's request for CNG, as described below.
To determine CNG support, the device uses the
ComfortNoiseNegotiation parameter and the codec’s SCE (silence
