[Users] How to change the expire parameter in a reply message of REGISTER?

[杨冬]

hi, all:
    I want to make a client to send the REGISTER update message in a
short time, which is used to prevent the NAT device to close the port
for the client. So I want to rewrite the reply message for REGISTER
and change the expire parameter to a value of my setting. How can I
achieve this?
    Thanks.
