Parameter Description
definition settings >
microsoft-ext
[EnableMicrosoftExt]
INVITE URI user part. Microsoft Office Communications Server
sometimes uses this proprietary parameter to indicate the extension
number of the called or calling party.
 [0] Disable (default)
 [1] Enable
For example, if a calling party makes a call to telephone number
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.

ader]

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).
configure voip > sip-
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 respons
e is sent immediately upon receipt
of INVITE request.
configure voip > sip-
definition settings > trans-
coder-present
[TransparentCoderPresenta
tion]
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).
