SIP User's Manual
Determines the SIP method used for session-timer updates.

[0] Re-INVITE = Uses Re-INVITE messages for session-timer
updates (default).

[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.
Determines whether the device removes the 'to' header tag from
final SIP failure responses to INVITE transactions.

[0] = Do not remove tag (default).

[1] = Remove tag.
Enables or disables the use of the 'rtcp' attribute in the outgoing
SDP.

[0] = Disable

[1] = Enable (default)
Defines the User-Part value of the Request-URI for outgoing SIP
OPTIONS requests. If no value is configured, the
parameter 'Username' value 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 value is an
empty string ('').
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 value is 0 (i.e., don't send AIS
alarms).
Determines the SIP signaling method for establishing and
transmitting a fax session after a fax is detected.

[0] No Fax = No fax negotiation using SIP signaling. Fax
transport method is according to the parameter
FaxTransportMode (default).

[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 (refer to 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 (refer to the Note below).
Notes:
