Hi all,

In an environment where the same user can be registered at the same time 
in multiple phones, how may I restrict users to only be able to make one 
call simultaneously? I mean... only make other call after hanging up the 
last one, never simultaneously made from different phones.

How may I implement that?

Regards,
Ricardo.
