Consider a multiparty conference call that includes geographically distant technical and marketing staffs and multiple representatives of a potential customer. In such a situation, it is often desirable for the staff to have online conversations at the same time as their phone conversation. They can use Instant Messaging to exchange tactical notes or data or to discuss other issues privately. The customer can use Instant Messaging to do the same.
Instant Messaging allows any number of participants to exchange quick notes during conference calls.
