The SIP registrar includes an expires parameter in the 200OK message exchanged sduring the registrations. That's what governs the length of the registration. Usually most devices are set to attempt re-register when the timer is half expired. If there is anywhere you would be able to change the expire parameter it would be in the registrar's settings.
