How to call an arbitrary TR-064 action?

This is my first post on OH community, so sorry in advance…

I successfully installed the TR-064 binding with my AVM Fritz!Box 7590. So far everything seems working.

As far as I understand TR-064 defines a set of standard actions, that can be called, and AVM added a set of additional actions (see https://avm.de/fileadmin/user_upload/Global/Service/Schnittstellen/AVM_TR-064_first_steps.pdf). Most of the available TR-064 actions are printed to OH-log (e.g. from OH community: https://community.openhab.org/uploads/short-url/7l31DLs8yFfBX2gOMJRn5WAf4US.log).

I assume the TR-064 binding uses some of the actions for the defined channels of the binding.

Is there any way to call a TR-064 action from a script?

To nail it down: I plan to use the TR-064 actions X_AVM-DE_DialNumber und X_AVM-DE_DialHangup from a rule, e.g. when one of my smoke sensors change status of the alarm channel.

	<action>
		<name>X_AVM-DE_DialNumber</name>
		<argumentList>
			<argument>
				<name>NewX_AVM-DE_PhoneNumber</name>
				<direction>in</direction>
				<relatedStateVariable>X_AVM-DE_PhoneNumber</relatedStateVariable>
			</argument>
		</argumentList>
	</action>
	<action>
		<name>X_AVM-DE_DialHangup</name>
	</action>


	<stateVariable sendEvents="no">
		<name>X_AVM-DE_PhoneNumber</name>
		<dataType>string</dataType>
	</stateVariable>
