# Configuring Log Call

{% hint style="info" %}
Please [support](https://docs.keyfax.biz/links/support "mention") for assistance editing your `MISExchange.xml` file.
{% endhint %}

The changes to simply log the call in MIS (where no task or repair has been generated in Keyfax) affect two areas:

1. **Keyfax Client**. You will need to install **Version 4.0.0.30 or greater**. 
2. **MIS mappings**. Upon launch/return Keyfax maps fields in / out of ActiveH. These mappings are contained within the configuration file `MISExchange.xml`. It will be necessary to establish **default values** for all Call-Level items (although these can be overridden by scripting) i.e. 

* Call Classification
* Call Type (aka Category)
* Call Source
* Call Priority

You will need to refer to MIS who should be able to advise regarding the numeric codes that are relevant to your installation.
