I think it is better not to use the static xml config files (inside folders directiry\dialplan). Instead, use one of the available programming languages (e.g. lua) for realization realtime directory\dialplan. Thus you will be given all the information you want (user registered\exists or not) from a database by your management script.

Subject: Re: [Freeswitch-users] How to check user in directory

Does user exist in user directory?
http://wiki.freeswitch.org/wiki/Mod_commands#user_exists

Is the user registered?
http://wiki.freeswitch.org/wiki/Function_sofia_contact

Quick example (untested but would probably work):

<!-- If the user doesn't exist, reject the call -->
<extension name="user_not_found">
  <condition field="${user_exists(id ${destination_number} $${domain})}" expression="false">
    <action application="hangup" data="UNALLOCATED_NUMBER" />
  </condition>
</extension>
<!-- If the user is registered, forward the call to them -->
<extension name="user_registered">
  <condition field="${sofia_contact(profile/${destination_number}@$${domain})}" expression="(.+)">
    <action application="set" data="hangup_on_bridge=true" />
    <action application="bridge" data="$1" />
  </condition>
</extension>
<!-- If the bridge fails, or the user wasn't registered, fall back to voicemail -->
<extension name="voicemail">
  <condition field="destination_number" expression=".*">
    <action application="voicemail" data="profile $${domain} ${destination_number}" />
  </condition>
</extension>

 Hello!

    I have a set of local users registered to freeswitch. So, when user
is not registered with switch I get USER_NOT_REGISTERED when route call
to it. But is there a way to know is user present in directory and not
registered, or even isn't in directory? I want to call voicemail in
first case and play 'invalid number' message in second. Is this possible?
