The packet spacing is normally 2 s; however, the spacing between the first and second packets can be changed with the calldelay command to allow additional time for a modem or ISDN call to complete. For use with the server command to reduce the time taken for initial synchronization. As of Red Hat Enterprise Linux 6.5, this is now a default option in the configuration file.
