Parameter Description
✔ If the received expiry time is less
than the minimum (as stated
above), the expiry time remains
unchanged. For example, if the
received expiry time in a
REGISTER message is 18 sec, the
device forwards the message with
this same expiry time (i.e., 18).
Note:
■ This feature does not apply to refresh
REGISTER or SUBSCRIBE
messages.
■ You can configure the device to change
the received expiry time before
forwarding it, using the
SBCUserRegistrationTime parameter.
