Incoming call
When I talk on the phone and receive an incoming call, I do not have the opportunity to park the first call in order to answer the second one. How can I change this setting?

If your carrier supports it, you can set up a conference call on your iPhone with up to five people.
The number of participants on a conference call — as well as the ability to add, merge, or disconnect individual callers — depends on your carrier. Contact your carrier for more information about your conference call options.
