Sometimes, calls are not answered by the targeted device. When this occcurs, it is called "Missed call". The call routing of missed calls means that if the call is missed, it gets redirected to another device. Ozeki Phone System XE has dial plans for the call routing of missed calls, which can be configured in many ways.
The guide below will show you how to make Dial plans for missed calls, and how to check the results in the Log window.
Step 1: Setting up SIP Extensions
Step 2: Making a dial plan
Step 3: Making a test call
Begin the guide with logging in to Ozeki Phone System XE (Figure 1).

You can handle missed calls from all sources and destinations. This guide will introduce the steps by using local extensions, so it is assumed that you have already added extensions to Ozeki Phone System XE.
If you need help, please visit the Extension setup guide.

To make a dial plan, go to the index page of Ozeki Phone System XE, and click on the Add button at the Dial plan section (Figure 3).
Figure 3 - Adding a dial plan
About the Missed Dial plans:
You can see four columns (as Figure 4 shows below):
Reason of the redirection:
You can select a situation when the call can be redirected, by a radio button:
Routing rule conditions:
The call will be sent from the source to the destination, if all of the set conditions suits the selected attributes. You can define conditions for the Callee, the Dialed number, the Caller ID and the Caller display attributes with the followings:
If there is a call which has passed all the set conditions, it can still contain the extra characters for the purpose to indicate something to the dial plans. Since you will not need those anymore, before the PBX sends the call to the destination, it can make preprocessings on the Dialed number, Caller ID, Caller display attributes:
In this guide, three SIP extensions will be used within Ozeki Phone System XE:
As the guide's the next step, select:

The conditions of the call has already been told, so make the call, and get information about it in the log of one of the SIP extensions. At this case, the log of the number "1001" SIP Extension is showed (Figure 5).
Figure 5 - SIP Extension log
You can follow all of the extensions' states here, and as you can see, the Outgoing call started message tells you; the call was initiated from the number "1001" extension and went to the number "1003" extension. Number "1003" missed the call (it was busy, as it was planned), and the call got redirected to the number "1100" SIP Extension, as you can see it in the Call established row, the called number is "1003", but the destination is the the number "1100" extension. The call has arrived after redirection, making the dial plans job done.
If a call (from any sources to any destinations) wasn't (maybe couldn't even be) answered
at the original destination, you can send that to local extensions (to a voicemail, for example), to another outside lines, or you can even disconnect that.
You can manage the missed calls by the parties' attributes (such as Caller ID, Dialed number etc.)
as well, but this time you have the option to redirect calls by the missed call's reason too, when
you are setting up the Dial plan(s).
This guide is usefull for anyone, who want to learn some information about the call routing of missed calls with Ozeki Phone System XE. If you follow this carefully, you are able to make your own SIP extensions, and your own Dial plan. After those you can test the dial plan, be making a test call.
