Proxy Set Connectivity
show voip proxy sets
status
[IPGroup_ProxySetCon
nectivity]
(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 388).
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 378).
 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 Call Routing Status'' on page
897.
 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_ClassifyByPr
oxySet]
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 677).
