CHAPTER68 Configuration Parameters Reference
Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
Note: If this feature is configured for a
specific IP Profile, the settings of this global
parameter is ignored for calls associated
with the IP Profile.
'SBC Proxy Registration Time'
configure voip > sbc settings >
sbc-prxy-rgstr-time
[SBCProxyRegistrationTime]
Defines the duration (in seconds) for which
the user is registered in the proxy database
(after the device forwards the REGISTER
message). This value is sent in the Expires
header. When set to 0, the device sends the
Expires header's value as received from the
user to the proxy.
The valid range is 0 to 2,000,000 seconds.
The default is 0.
configure voip > sbc settings >
sbc-rand-expire
[SBCRandomizeExpires]
Enables the device to change the expiry
time in the Expires header of SIP 200 OK
responses for user registration or
subscription requests.
The feature is useful in scenarios where
multiple users may refresh their registration
or subscription simultaneously, causing the
device to handle many such sessions at a
given time. This may result in an overload of
the device (reaching maximum session
capacity), preventing the establishment of
new calls or preventing the handling of
some user registration or subscription
requests. However, when this feature is
enabled, the device assigns a random
expiry time to each user registration or
subscription, ensuring future user
registration and subscription requests are
more distributed over time (i.e., do not all
occur simultaneously).
The valid value is 0 (disabled) to 20 (any
value from 1 to 20 is considered enabled).
The default is enabled (10). If disabled (i.e.,
0), the device does not change the expiry
time. If enabled, the device assigns a
random expiry time as follows:
■ If the received expiry time is less than
610 sec, the device reduces the time by
up to 10 sec. For example, if the
received expiry time is 110 sec, the
device reduces it to anywhere between
100 (i.e., 110 – 10) and 110 sec.
