 *             instead of UDP package (bogdan)
 * 2006-11-28  Added statistics tracking for the number of accepted/rejected
 *             registrations, as well as for the max expiry time, max contacts,
 *             and default expiry time. (Jeffrey Magder - SOMA Networks)
 * 2007-02-24  sip_natping_flag moved into branch flags, so migrated to
