Leg is a connection (between equipments). In a network diagram, a connection look like a leg.

Some of the FreeSwitch DialPlan tools like transfer or blind transfer user notions of leg A - as a person who dialed (caller) log B - as a person who was dialed (callee)

As a good example is bind_meta_app

So for example you can execute some command or do an action if a key was pressed by (caller (leg) a or callee (leg) b or any leg in this case caller or callee ab)
