Mediant 2600 E-SBC
Parameter Description
The source IP Group is set to the default IP Group
associated with this SRD.
If the source SRD is ID 0, then source IP Group ID 0 is
chosen. In case of any other SRD, then the first IP Group
associated with this SRD is chosen as the source IP Group
or the call. If no IP Group is associated with this SRD, the
Web: SBC No Answer Timeout
CLI: 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.
CLI: configure voip/sbc general-
setting/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.
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
[SBCInDialogSubscribeRoute
Mode]
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:
