Starting from the WMS 3.0 Wildix introduced the multicast (http://en.wikipedia.org/wiki/Multicast) RTP transmission for the paging function, the phones configured in a paging group are listening to a multicast address so many phones are concurrently
able to reproduce the audio.
The same function code (91 by default) used to start a paging call could be used by one of the "receiving" phones to cancel the paging call and start a one to one conversation.
The usage scenario is the following:
a secretary uses the 911 function code to start a paging call (group 1) and reach the director wherever he is, the director can hear the voice and pickup the call calling the 91 (it works also with a speed dial key)
