7. How Calls are Processed

How Calls are Processed

In the following discussion, SIP and PSTN endpoints/interfaces are interchangeable, and

they may be used on no, one, or two sides of the call.

Diva SIPcontrol uses an endpoint-based approach to process calls, which means that every

PSTN interface and every configured SIP peer is considered as a single endpoint. The

endpoint holds Diva SIPcontrol settings for the respective PSTN interface or SIP peer. Each

call originates at a specific endpoint (on the SIP side after assigning the SIP call request to

one of the configured peers) and needs a route to find its designated endpoint (the

destination). Thus, the most simple configuration needs two endpoints of any type and one

route, as shown in red in the graphic below.

This graphic shows that an endpoint is only a virtual object of a real device. The endpoint

holds the settings for the corresponding device. For example, if a call should be routed from

SIP Device 3 to PSTN Device 2 as marked red in the graphic, then the:

 Settings of SIP Device 3 need to be configured as a SIP peer endpoint in the SIP

Peers section.

 Settings PSTN Device 2 needs to be configured as a PSTN endpoint in the PSTN

Interfaces section.

 Condition "called address is 3456" needs to be configured in the Routing section to

route the call to the correct device.

For example, if you have a SIP or PSTN Device 4 with no endpoints configured in Diva

SIPcontrol, you cannot establish a call, because Diva SIPcontrol will not know the settings of

the device.
