Table 5-8: General Parameters (Protocol Definition)
If enabled, the gateway sends 183 Session Progress response with SDP
(instead of 180 Ringing), allowing the media stream to be set up prior to
the answering of the call.
[0] Disable = Early Media is disabled (default).
[1] Enable = Enables Early Media.
Note: To send 183 response you must also set the parameter
ProgressIndicator2IP to 1. If it is equal to 0, 180 Ringing response is sent.
Determines the timeout (in seconds) for keeping a Re-INVITE message
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).
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.
Defines the SIP method used for session-timer updates.
Valid options include:
[0] Re-Invite = Use Re-INVITE messages for session-timer updates
(default).
[1] Update = Use UPDATE messages.
Notes:
The gateway can receive session-timer refreshes using both methods.
The UPDATE message used for session-timer purposes is excluded
from the SDP body.
[0] Disabled = None (default)
[1] Adding PAsserted Identity
[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>.
