Table 5-8: General Parameters (Protocol Definition)
Parameter Description
Enable Early Media
[EnableEarlyMedia]
If enabled, the gateway sends 183 Session Progress response with SDP

the answering of the call.
ƒ
[0]
Disable = Early Media is disabled (default).
ƒ
[1]
Enable = Enables Early Media.

Session-Expires Time
[SIPSessionExpires]

alive within a SIP session. The SIP session is refreshed each time this
timer expires. The SIP method used for session-timer updates is
determined according to the parameter SessionExpiresMethod.
The valid range is 1 to 86400 sec. The default is 0 (i.e., not activated).
Minimum Session-
Expires
[MINSE]
Defines the time (in seconds) that is used in the Min-SE header. This
header defines the minimum time that the user agent supports for session
refresh.
The valid range is 10 to 100000. The default value is 90.
Session Expires Method
[SessionExpiresMethod
]
Defines the SIP method used for session-timer updates.
Valid options include:
ƒ

(default).

from the SDP body.
Asserted Identity Mode
[AssertedIdMode]
ƒ
[0]
Disabled = None (default)
ƒ
[1]
Adding PAsserted Identity
ƒ
[2]
Adding PPreferred Identity
The Asserted ID mode defines the header that is used in the generated
INVITE request. The header also depends on the calling Privacy: allowed
or restricted.
The P-asserted (or P-preferred) headers are used to present the
originating party's Caller ID. The Caller ID is composed of a Calling
Number and (optionally) a Calling Name.
P-asserted (or P-preferred) headers are used together with the Privacy
header. If Caller ID is restricted, the 'Privacy: id' is included. Otherwise for
allowed Caller ID, the 'Privacy: none' is used. If Caller ID is restricted
(received from Tel or configured in the gateway), the From header is set to
<anonymous@anonymous.invalid>.
