12- Configure Incoming Calls

The XN120 supports two methods of handling incoming SIP calls; normal (non-DDI) or DDI.

This guide explains the general operation only, for an explanation of every option refer to the XN120 Features

Manual 991434-5.

If the SIP network does not supply any DDI digits then the BRI lines can be routed in exactly the same way that

you would route an analogue trunk. Refer to the XN120 Getting Started Guide for more detail.

In brief,

Route each VOIPU line to an Incoming Ring Group (IRG) in program 22-05-01. A line can route to a

different IRG in each night mode.

IRG.
