We can use voicecall path indeed, however this script will not be enough 
to clear all the remote parties of a multiparty call at once.
For instance, I have a 3GPP test case that ask me to do this:
     - create a multiparty call with 3 parties
     - create a new single call
     - clear multiparty call in held

I could either use the hangup-call-state script (with held argument) 
either create a new script using HangupMultiparty() method from 
voicecallmanager API (like there is a hangup-all script).
One of those scripts would avoid to call thrice hangup-call for a 
multiparty call with 3 party for instance.

Kind regards,
Guillaume
