How do I take a call while on another call?

When I am on a call and somebody calls how do I take it without hanging up on first person

Dunno. You didnt bother to give the make and model of the phone.

All we'd do is look for the manual and, if we find it, read it and post suggestions of what page to look at.

All of which you can do
