The method of starting an ad-hoc conference depends on the particular phone or softphone being used. It will typically involve putting an existing call on hold, making an additional call and then selecting a conference option. The same method can usually be used for adding additional parties to an existing conference.

If necessary, controls for starting and adding users to an ad-hoc conference can be created using short codes and programmable buttons. Note that when used to add a party to an existing conference, these controls also work with existing meet-me conferences.
