Parameter Description
Proxy Set Connectivity
show voip proxy sets status
[IPGroup_ProxySetConnecti
vity]
(Read-only field) Displays the connectivity status with Server-type IP
Groups. As the Proxy Set defines the address of the IP Group, the
connectivity check (keep-alive) by the device is done to this address.
"NA": Functionality is not applicable due to one of the following:
User-type IP Group.
Server-type IP Group, but the keep-alive mechanism of its'
associated Proxy Set is disabled.
"Not Connected": Keep-alive failure (i.e., no connectivity with the IP
Group).
"Connected": Keep-alive success (i.e., connectivity with the IP
Group).
The connectivity status is also displayed in the Topology View page
(see ''Building and Viewing SIP Entities in Topology View'' on page
377).
Note:
The feature is applicable only to Server-type IP Groups.
To support the feature, you must enable the keep-alive mechanism
of the Proxy Set that is associated with the IP Group (see
''Configuring Proxy Sets'' on page 367).
If the Proxy Set is configured with multiple proxies (addresses) and
at least one of them is "alive", the displayed status is "Connected".
To view the connected proxy server, see ''Viewing Proxy Set
StatusStatus'' on page 896.
The "Connected" status also applies to scenarios where the device
rejects calls with the IP Group due to low QoE (e.g., low MOS),
despite connectivity.
SBC General
Classify By Proxy Set
classify-by-proxy-set
[IPGroup_ClassifyByProxyS
et]
Enables classification of incoming SIP dialogs (INVITEs) to Server-
type IP Groups based on Proxy Set (assigned using the
IPGroup_ProxySetName parameter).
[0] Disable
[1] Enable = (Default) The device searches the Proxy Sets table for
a Proxy Set that is configured with the same source IP address as
that of the incoming INVITE (if host name, then according to the
dynamically resolved IP address list). If such a Proxy Set is found,
the device classifies the INVITE as belonging to the IP Group
associated with the Proxy Set.
Note:
The parameter is applicable only to Server-type IP Groups.
For security, it is recommended to classify SIP dialogs based on
Proxy Set only if the IP address of the IP Group is unknown. In
other words, if the Proxy Set associated with the IP Group is
configured with an FQDN. In such cases, the device classifies
incoming SIP dialogs to the IP Group based on the DNS-resolved
IP address. If the IP address is known, it is recommended to use a
Classification rule instead (and disable the Classify by Proxy Set
feature), where the rule is configured with not only the IP address,
but also with SIP message characteristics to increase the strictness
of the classification process (see Configuring Classification Rules
on page
687).
