Parameter Description
configure voip >
sip-definition
settings >
microsoft-ext
[EnableMicrosoftExt]
■ [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.,
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.

response and a subsequent 18x response. If a 18x response is not
received within this timeout period, the call is disconnected.

(i.e., 32 sec).

attribute is used in the SDP to indicate the use of echo cancellation.
■ [0] = (Default) The 'ecan' attribute appears on the 'a=gpmd' line.
■ [1] = The 'ecan' attribute appears as a separate attribute.
■ [2] = The 'ecan' attribute is not included in the SDP.
■ [3] = The 'ecan' attribute and the 'vbd' parameter are not included
in the SDP.
Note: The parameter is applicable only when the IsFaxUsed

device as result of modem or fax tone detection.
