User's Manual
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.
Notes:

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 Software
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 proxies) that can
forward the SIP request. The Max-Forwards value indicates the
remaining number of times this request message is allowed to be
forwarded. This count is decremented by each server that forwards the
request.
The parameter affects the Max-Forwards header in the received
message as follows:

If the received header's original value is 0, the message is not
passed on and is rejected.

If the received header's original value is less than the parameter's
value, the header's value is decremented before being sent on.

If the received header's original value is greater than the parameter's
value, the header's value is replaced by the user-defined
parameter's value.
The valid value range is 1-70. The default is 10.
