User's Manual 43. Configuration Parameters Reference
Parameter Description
Web: Minimum Session-
Expires
EMS: Minimal Session
Refresh Value
[MinSE]
Defines the time (in seconds) that is used in the Min-SE header. This
header defines the minimum time that the user agent refreshes the
session.
The valid range is 10 to 100,000. The default is 90.
Web/EMS: Session
Expires Disconnect Time
CLI: session-exp-
disconnect-time
[SessionExpiresDisconn
ectTime]
Defines a session expiry timeout. The device disconnects the session
(sends a SIP BYE) if the refresher does not send a refresh request
before one-third (1/3) of the session expires time, or before the time
configured by this parameter (the minimum of the two).
The valid range is 0 to 32 (in seconds). The default is 32.
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.
[RemoveToTagInFailureR
esponse]
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 endpoint number is
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: 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-
law/µ-law with adaptations (see the Note below).
Notes:
 Fax adaptations (for options 2 and 3):

Echo Canceller = On

Silence Compression = Off
 Echo Canceller Non-Linear Processor Mode = Off
