Properties
Variable to receive conference handle: When a conference is successfully created, TeleFlow will store an identifier for this conference in the variable you provide. This identifier is required in order to join members to the conference (see the Join Conference step) or to close the conference when it is completed (see the Close Conference step).
Maximum number conference seats: This setting determines the maximum number of members your conference will hold. The term "seats" draws an analogy between a conference room and a telephone conference. You do not need to add the maximum number of members to your conference in order to begin a conference. However, you cannot add more members than you have seats defined. This is required because conferencing is resource-intensive, and conference resources must be set aside during the conference setup.
Echo cancellation: Echo cancellation prevents each member's audio from being echoed back to him down the "ear path" of the telecom circuit. It consumes more resources from your telephony card(s), and therefore is not recommended, unless your participants find the echo unpleasant.
DTMF clamping: DTMF clamping prevents a touch-tone pressed by one conference participant being heard by all participants in the conference. This is especially important if your application is programmed to use TT input to exit a member and provide him or her with other options. For example, you may wish the star key (*) to allow a participant to leave the conference to select a different conference to join. With DTMF clamping OFF, all participants would be pushed out of the conference if just one of them pressed star.
Tone clamping: If your telecom circuit uses different tones than DTMF, you made need to turn on Tone clamping instead of, or in addition to DTMF clamping.
Action Steps
Failure: A failure can occur if telephony hardware lacks sufficient resources to start the conference with the parameters specified. This may be because the hardware lacks the capabilities for a conference, or because the resources are consumed by other conferences.
