How to manage multiple phone calls at the same time

This guide explores how you can setup Ozeki VoIP SIP SDK for managing multiple phone calls professionally.

Multiple phone calls

Telephoning nowadays is not only about calling somebody to tell some news but also a tool for making business calls. A company telephone line has to support more than one incoming call at the same time (Figure 1).

The support of multiple calls means that the telephone client can handle more than one call at the same time. This does not necessarily mean that the callee hears all the calls simultaneously but the calls are put into lines and the company telephone agent transfers the calls to other telephones within the company system. While the company telephone network seems to be a single telephone end-point from outside.

Ozeki VoIP SIP SDK has an illustrious support for multiple calls, you only have to handle them. There are flags that indicate the number of the actual calls, the selected (active) call and the incoming call ID in case of an incoming call.
