Parameter Description
Thus, the parameter is useful when a UA
does not support session refresh requests
or does not support the indication of who
performs session refresh requests. In such
a scenario, the device can be configured to
perform the session refresh requests.
■ [0] = (Default) Remote Refresher. The
UA (proxy) performs the session refresh
requests. The device indicates this to
the UA by sending the SIP message
with the 'refresher=' parameter in the
Session-Expires header set to 'uas'.
■ [1] = SBC Refresher. The device
performs the session refresh requests.
The device indicates this to the UA by
sending the SIP message with the
'refresher=' parameter in the Session-
Expires header set to 'uac'.
Note: The time values of the Session-
Expires (session refresh interval) and Min-
SE (minimum session refresh interval)
headers can be configured using the
SBCSessionExpires and SBCMinSE
parameters, respectively.
'User Registration Grace Time'
configure voip > sbc settings >
sbc-usr-reg-grace-time
[SBCUserRegistrationGraceTime]
Defines additional time (in seconds) to add
to the registration expiry time of users that
are registered with the device.
The valid value is 0 to 2,000,000. The
default is 0.
For more information, see Registration
Refreshes.
'DB Routing Search Mode'
configure voip > sbc settings > sbc-db-route-
mode
[SBCDBRoutingSearchMode]
Defines the method for searching a
registered user in the device's User
Registration database when a SIP INVITE
message is received for routing to or from a
user. If the registered user is found (i.e.,
destination URI in INVITE), the device
routes the call to the user's corresponding
contact address specified in the database.
■ [0] All permutations = (Default)
✔ To User: Device searches for the
user in the database using the
entire Request-URI (user@host). If
not found, it searches for the user
part of the Request-URI. For
example, it first searches for
"4709@joe.company.com" and if
not found, it searches for "4709".
