User's Manual
(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 405. 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.
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.
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.
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 (address) is
determined by the device's keep-alive mechanism for the
Proxy Set that was used to route the initial SUBSCRIBE.
Note: For this feature to be functional, ensure the following:

Keep-alive mechanism is enabled for the Proxy Set ('Proxy
Keep-Alive' parameter is set to any value other than
Disable).

Load-balancing between proxies is disabled ('Proxy Load
Balancing Method' parameter is set to Disable).
Defines the Max-Forwards SIP header value. The Max-
Forwards header is used to limit the number of servers (such as
