How do I install a headset with my phone?

In most cases, all headsets will plug into the headset port found on the bottom of your phone or on the side.  This port is typically indicated by a icon looking like a pair of headphones. 

If you are using a cordless headset, then typically it has a base or base unit that would plug into this port. 

Please also refer to your phone's specific user manual for additional information.
