    |||||||||||||||||||||
    
 Wireless Master Slave Intercom systems (1000 
    line): You can communicate between the master and slaves without any wiring. 
    The main attraction of the master-slave system is you can use up to 1000 number 
    of slaves with one mater set. You can dial to the required slaves from the master 
    unit and can communicate. For to make a call from the slaves to the master, 
    just lift the handset of the slaves. As the slaves have no inter-dialing facility, 
    it is not possible to communicate between the slaves. You can also transfer 
    the telephone calls from master to slave with extra cost.
