Parameter Description
SBC Max Call Duration
configure voip > sbc settings > sbc-mx-call-
duration
[SBCMaxCallDuration]
Defines the maximum duration (in minutes) per SBC
call (global). If the duration is reached, the device
terminates the call.
The valid range is 0 to 35,791, where 0 is unlimited
duration. The default is 0.
Note: You can also configure this functionality per
specific calls, using IP Profiles
(IpProfile_SBCMaxCallDuration). For a detailed
description of the parameter and for configuring this
functionality in the IP Profiles table, see ''Configuring
IP Profiles'' on page 423. If this functionality is
configured for a specific IP Profile, the settings of this
global parameter is ignored for calls associated with
the IP Profile.
SBC No Answer Timeout
configure voip > sbc settings > sbc-no-arelt-
timeout
[SBCAlertTimeout]
Defines the timeout (in seconds) for SBC outgoing
(outbound IP routing) SIP INVITE messages. If the
called IP party does not answer the call within this
user-defined interval, the device disconnects the
session. The device starts the timeout count upon
receipt of a SIP 180 Ringing response from the called
party. If no other SIP response (for example, 200 OK)
is received thereafter within this timeout, the call is
released.
The valid range is 0 to 3600 seconds. the default is
600.
configure voip > sbc settings > num-of-
subscribes
[NumOfSubscribes]
Defines the maximum number of concurrent SIP
SUBSCRIBE sessions permitted on the device.
The valid value is any value between 0 and the
maximum supported SUBSCRIBE sessions. When
set to -1, the device uses the default value. For more
information, contact your AudioCodes sales
representative.
Note:
For the parameter to take effect, a device reset is
required.
The maximum number of SUBSCRIBE sessions
can be increased by reducing the maximum
number of SBC channels in the License Key. For
every reduced SBC session, the device gains two
SUBSCRIBE sessions.
configure voip > sbc settings > sbc-dialog-
subsc-route-mode
[SBCInDialogSubscribeRouteMode]
Enables the device to route in-dialog, refresh SIP
SUBSCRIBE requests to the "working" (has
connectivity) proxy.
[0] = (Default) Disable – the device sends in-
dialog, refresh SUBSCRIBES according to the
address in the Contact header of the 200 OK
response received from the proxy to which the
initial SUBSCRIBE was sent (as per the SIP
standard).
[1] = Enable – the device routes in-dialog, refresh
SUBSCRIBES to the "working" proxy (regardless
of the Contact header). The "working" proxy
