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.,
e 622125519100 104 ). 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.

18x-timeout
[TimeoutBetween100And
18x]
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).

[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.

[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
suppression setting) using the CodersGroup parameter.
If the ComfortNoiseNegotiation parameter is enabled, then the following
