The documentation says:
   iburst
          When the server is unreachable, send a burst of eight packets
          instead of the usual one. 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. This option is valid only with
          the server command and type s addresses. It is a recommended
          option with this command.

So I see no reason to remove this.
