Integration

CSTA III (XML) is required to provide the integration between MX-ONE and Lync Server for Remote Call Control as shown in the figure below.

The telephony feature commands are sent from the Lync 2013 client through the Microsoft Lync Server 2013 to the internal MX-ONE CSTA server as CSTA III messages over SIP, so called user agent CSTA (uaCSTA). The internal MX-ONE CSTA server analyzes the requests and maps them to the corresponding CSTA commands towards MX-ONE, which will then carry out the requests.

Figure 1 - Integration via Remote Call Control (RCC) between MX-ONE and Lync Server 2013

With Microsoft Lync Server 2013 integration, it is possible from Lync 2013 client (Remote Call Control Only) to manage calls and talk using any fixed and remote extensions within the MX-ONE.

The features that a Lync 2013 client can manage when integrate with MX-ONE using RCC are:

Make an outgoing call

Answer an incoming call

Transfer a call to another user (monitored transfer with current conversations)

Single step transfer

Forward an incoming call to an internal number (internal and private network extensions)

Forward an incoming call to an external number

Redirect an incoming call

Place calls on hold

Alternate (toggle) between multiple concurrent calls

Answer a second call while already in a call.
