7.1 Conferencing Telephones Together

When your telephone is joined together with several other telephones on the same call, the effect is called conferencing. You can make conference calls that involve up to five parties, including you as the originating party, in any combination of outside lines and intercom parties. For example, you can conference three outside lines and two intercom parties or four outside lines and one intercom party or five intercom parties—the combinations are up to you.

If you are involved in a conference call with two outside lines, you can drop out of this established conference call and leave the outside lines in the conference with each other. This is known as an unsupervised conference call.

NOTE: When setting up a conference call with outside lines and internal telephones, you must call the outside lines first.
