UML Activity Diagram
The Activity CatchDialN receives SignalEvents corresponding to numbered buttons on a telephone using AcceptEventAction items, then invokes a usage of Activity DialN(n:int[1]) via a CallBehaviorAction:

We'll be processing many digits during the dialing of an entire phone number, so we need to embed this in a higher level "loop" as shown next

Notes
Snippets (quotes/extracts)
  [UML-2.5.1] If an AcceptEventAction is used in an Activity, there are special rules for when it is enabled ..
  [UML-2.5.1] If the AcceptEventAction has no incoming edges, by the usual rules, it is enabled when its immediately containing Activity (or StructuredActivityNode) begins execution.
  [UML-2.5.1] AcceptEventAction is an Action with Triggers for one or more Events. When an AcceptEventAction is executed, it waits for an Event occurrence to be dispatched from the event pool of the context object for its execution that matches one of its Triggers.
  [UML-2.5.1] An AcceptEventAction is a wait point ... except only the AcceptEventAction waits, rather than the whole Activity (Activities can have other Actions executing while AcceptEventActions are waiting).
  [UML-2.5.1] An AcceptEventAction with a trigger for a SignalEvent is informally called an accept signal action.
  [UML-2.5.1] If it has isUnmarshall=true, then it must have result OutputPins corresponding to each of the attributes of the Signal of the SignalEvent (in order), and the attribute values of the Signal instance associated with an accepted SignalEvent occurrence ...
  [UML-2.5.1] A CallBehaviorAction is a CallAction that invokes a Behavior directly, rather than calling a BehavioralFeature that, in turn, results in the invocation of a Behavior.
  [UML-2.5.1] The argument Pins of a CallAction are matched, in order, to the sublist of input Parameters, while the result Pins are matched, in order, to the sublist of output Parameters.
