Hi i just came on this site and it is really great.  I am looking for some advice.  I am in college and need to do a project.  Hoping to do one on VOIP and set up an actual voip system and hope to use 3cx. 

I would like to somehow 'hack' into the voip system or intrude and be able to show this and then provide a solution or show i solved this security threat.  I am a total newbie to this kind of area so any help or guidance is REALLY appreciated.  Apologies if i haven't posted this in the right section.

Thanks.
