SIP User's Manual 3. Web-Based Management
Parameter Description
redundancy mode is disabled.

When the active proxy doesn't respond to INVITE messages
sent by the device, the proxy is tagged as 'offline'. The behavior
is similar to a Keep-Alive (OPTIONS or REGISTER) failure.
Web: Proxy Keep Alive Time
EMS: Keep Alive Time Defines the Proxy keep-alive time interval (in seconds) between
Keep-Alive messages. This parameter is configured per Proxy Set.
The valid range is 5 to 2,000,000. The default value is 60.
[ProxyKeepAliveTime]
Note:
Web/EMS: Is Proxy Hot-Swap
This parameter is applicable only if the parameter
EnableProxyKeepAlive is set to 1 (OPTIONS). When the
parameter EnableProxyKeepAlive is set to 2 (REGISTER), the
time interval between Keep-Alive messages is determined by the
parameter RegistrationTime.
Enables the Proxy Hot-Swap redundancy mode per Proxy Set.
[IsProxyHotSwap]

[0]

No = Disabled (default).
[1]
If Proxy Hot-Swap is enabled, the SIP INVITE/REGISTER
message is initially sent to the first Proxy/Registrar server. If there
is no response from the first Proxy/Registrar server after a specific
number of retransmissions (configured by the parameter
HotSwapRtx), the INVITE/REGISTER message is resent to the
next redundant Proxy/Registrar server.
Yes = Proxy Hot-Swap mode is enabled.
3.3.4.3.3 Configuring the IP Groups
The 'IP Group Table' page allows you to create up to nine logical IP entities called IP
Groups . These IP Groups are used for call routing. The IP Group can be used as a
destination entity in the 'Tel to IP Routing' table, and Serving IP Group ID in the 'Hunt
Group Settings' (refer to ‘‘Configuring the Hunt Group Settings’’ on page
150 ) and 'Account'
(refer to ''Configuring the Account Table'' on page 102 ) tables. These call routing tables are
used for identifying the IP Group from where the INVITE is sent for obtaining a digest
user/password from the 'Account' table if there is a need to authenticate subsequent SIP
requests in the call. The IP Group can also be implemented in IP-to-Tel call routing as a
source IP Group.
The IP Groups can be assigned various entities such as a Proxy Set ID, which represents
an IP address (created in ''Configuring the Proxy Sets Table'' on page
95 ). You can also
assign the IP Group with a host name and other parameters that reflect parameters sent in
the SIP Request From\To headers.
Notes:
•
By default, if you disable the use of a proxy (i.e., IsProxyUsed is set to 0),
then only one IP Group is defined (and working with multiple IP Groups is
not valid).
•
You can also configure the IP Groups table using the ini file table
parameter IPGroup (refer to ''SIP Configuration Parameters''
252
on page
).
