Mediant 2600 E-SBC
Parameter Description
nectTime]
send a refresh request within the new timeout, the device disconnects the
session (i.e., sends a SIP BYE).
For example, if you configure the parameter to 32 seconds and the
Session-Expires value is 180 seconds, the session timeout occurs 148
seconds (i.e., 180 minus 32) after the last session refresh. If the Session-
Expires header value is 90 seconds, the timeout occurs 60 seconds after
the last refresh. This is because 90 minus 32 is 58 seconds, which is less
than one third of the Session-
Expires value (i.e., 60/3 is 30, and 90 minus
30 is 60).
The valid range is 0 to 32 (in seconds). The default is 32.
Web/EMS: Session
Expires Method
CLI: session-exp-method
[SessionExpiresMethod
]
Determines the SIP method used for session-timer updates.
 [0] Re-INVITE = (Default) Uses re-INVITE messages for session-
timer
updates.
 [1] UPDATE = Uses UPDATE messages.
Notes:
 The device can receive session-timer refreshes using both methods.
 The UPDATE message used for session-timer is excluded from the
SDP body.
[RemoveToTagInFailure
Response]
Determines whether the device removes the ‘to’ header tag from final SIP
failure responses to INVITE transactions.
 [0] = (Default) Do not remove tag.

[1]
= Remove tag.
[EnableRTCPAttribute]
Enables the use of the 'rtcp' attribute in the outgoing SDP.
 [0] = Disable (default)

[1]
= Enable
EMS: Options User Part
[OPTIONSUserPart]
Defines the user part value of the Request-URI for outgoing SIP
OPTIONS requests. If no value is configured, the
configuration parameter
‘Username’ valueis used.
A special value is ‘empty’, indicating that no user part in the Request-URI
(host part only) is used.
The valid range is a 30-character string. By default, this value is not
defined.
Web: Fax Signaling
Method
EMS: Fax Used
CLI: fax-sig-method
[IsFaxUsed]
Global parameter that defines the SIP signaling method for establishing
and transmitting a fax session when the device detects a fax. You can
also configure this functionality per specific calls, using IP Profiles
(IpProfile_IsFaxUsed). For a detailed description of this parameter and
for configuring this functionality in the IP Profile table, see ''Configuring IP
Profiles'' on page 297.
Note: If this functionality is configured for a specific IP Profile, the
settings of this global parameter is ignored for calls associated with the IP
Profile.
[HandleG711asVBD]
Enables the handling of G.711 as a G.711 Voice Band Data (VBD) coder.
 [0] = (Default) Disable. The device negotiates G.711 as a regular
audio coder and sends an answer only with G.729 coder. For
example, if the device is configured with G.729 and G.711 VBD
coders and it receives an INVITE with an SDP offer containing G.729
and “regular” G.711 coders, it sends an SDP answer containing only
the G.729 coder.
 [1] = Enable. The device assumes that the G.711 coder received in
the INVITE SDP offer is a VBD coder. For example, if the device is
