Version 6.6 701 Mediant 3000
User's Manual 53. Configuration Parameters Reference
Parameter Description
Web/EMS: Session
Expires 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
Note: This parameter is applicable only to the IP-to-IP/GW application.
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. The default is an empty string
(‘’).
Web: TDM Over IP
Minimum Calls For Trunk
Activation
EMS: TDM Over IP Min
Calls For Trunk Activation
[TDMOverIPMinCallsFor
TrunkActivation]
Defines the minimal number of SIP dialogs that must be established
when using TDM Tunneling to consider the specific trunk as active.
When using TDM Tunneling, if calls from this defined number of B-
channels pertaining to a specific Trunk fail (i.e., SIP dialogs are not
correctly set up), an AIS alarm is sent on this trunk toward the PSTN
and all current calls are dropped. The originator gateway continues the
INVITE attempts. When this number of calls succeed (i.e., SIP dialogs
are correctly set up), the AIS alarm is cleared.
The valid range is 0 to 31. The default is 0 (i.e., don't send AIS alarms).
[TDMoIPInitiateInviteTim
e] Defines the time (in msec) between the first INVITE issued within the
same trunk when implementing the TDM tunneling application.
The valid value range is 2000 to 4000. The default is 2000.
[TDMoIPInviteRetryTime
] Defines the time (in msec) between call release and a new INVITE
when implementing the TDM tunneling application.
The valid value range is 30,000 to 60,000. The default is 30,000.
Web: Fax Signaling
Method
EMS: Fax Used
[IsFaxUsed]
Determines the SIP signaling method for establishing and transmitting a
fax session after a fax is detected.

[0] No Fax = (Default) No fax negotiation using SIP signaling. Fax
transport method is according to the parameter FaxTransportMode.

[1] T.38 Relay = Initiates T.38 fax relay.

[2] G.711 Transport = Initiates fax/modem using the coder G.711 A-
law/Mu-law with adaptations (see Note below).

[3] Fax Fallback = Initiates T.38 fax relay. If the T.38 negotiation
fails, the device re-initiates a fax session using the coder G.711 A-
