AudioCodes MSBG Series User Manual

User's Manual 350 Document #: LTRT-27045
Mediant 1000B Gateway & E-SBC
Parameter Description
to this Proxy Set fails, the TLS Context is not used. Instead, the
device uses the TLS Context configured for the SIP Interface
(see ''Configuring SIP Interfaces'' on page
326
) used for the call;
otherwise, the default TLS Context (ID 0) is used.
 Outgoing calls: If the 'Transport Type' parameter is set to TLS
and the outgoing call is sent to an IP Group that is associated
with this Proxy Set, this TLS Context is used. Instead, the
device uses the TLS Context configured for the SIP Interface
used for the call; otherwise, the default TLS Context (ID 0) is
used. If the 'Transport Type' parameter is set to UDP
, the device
uses UDP to communicate with the proxy and no TLS Context is
used.
To configure TLS Contexts, see ''Configuring TLS Certificate
Contexts'' on page 103.
Keep Alive
Proxy Keep-Alive
proxy-enable-keep-alive
[ProxySet_EnableProxyKeepAli
ve]
Enables the device's Proxy Keep-Alive feature, which checks
communication with the proxy server.
 [0] Disable (default).
 [1] Using OPTIONS = Enables the Proxy Keep-Alive feature
using SIP OPTIONS messages. The device sends an OPTIONS
message every user-defined interval, configured by the 'Proxy
Keep-Alive Time' parameter (in this table). If the device receives
a SIP response code that is configured in the 'Keep-Alive
Failure Responses' parameter (in this table), the device
considers the proxy as down. You can also configure whether to
use the device's IP address or string name ("gateway name") in
the OPTIONS message (see the UseGatewayNameForOptions
parameter).
 [2] Using REGISTER = Enables the Proxy Keep-Alive feature
using SIP REGISTER messages. The device sends a
REGISTER message every user-defined interval, configured by
the RegistrationTime parameter (Gateway application) or
SBCProxyRegistrationTime parameter (SBC application). Any
SIP response from the proxy - success (200 OK) or failure (4xx
response) - is considered as if the proxy is "alive". If the proxy
does not respond to INVITE messages sent by the device, the
proxy is considered as down (offline).
If you enable the Proxy Keep-Alive feature, the device can operate
with multiple proxy servers (addresses) for redundancy and load
balancing (see the 'Proxy Load Balancing Method' parameter).
Note:
 For Survivability mode for User-type IP Groups, the parameter
must be enabled (1 or 2).
 If the parameter is enabled and the proxy uses the TCP/TLS
transport type, you can enable CRLF Keep-Alive feature, using
the UsePingPongKeepAlive parameter.
Proxy Keep-Alive Time
proxy-keep-alive-time
[ProxySet_ProxyKeepAliveTime
]
Defines the interval (in seconds) between keep-alive messages
sent by the device when the Proxy Keep-Alive feature is enabled
(see the 'Proxy Keep-Alive' parameter in this table).
The valid range is 5 to 2,000,000. The default is 60.
Note: The parameter is applicable only if the 'Proxy Keep-Alive'
parameter is set to Using Options.
