Mediant 500L MSBR
Parameter Description
setting/num-of-subscribes
[NumOfSubscribes]
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 this 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.
CLI: configure voip/sbc general-
setting/sbc-dialog-subsc-route-
mode
[SBCInDialogSubscribeRouteM
ode]
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 ('Enable
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
).
CLI: sbc-max-fwd-limit
[SBCMaxForwardsLimit]
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.
This 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 this
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.
Web: SBC Session-Expires
CLI: sbc-sess-exp-time
[SBCSessionExpires]
Defines the SBC session refresh timer (in seconds) in the
Session-Expires header of outgoing INVITE messages.
The valid value range is 90 (according to RFC 4028) to 86400.
The default is 180.
Web: Minimum Session-Expires
CLI: min-session-expires
Defines the minimum amount of time (in seconds) between
session refresh requests in a dialog before the session is
considered timed out. This value is conveyed in the SIP Min-SE
