[OpenSIPS-Users] preventing access to my sip network by other programs?

[xpro6000]

I want use opensips for a part of my project that needs communication
between users.

I'm concerned about others reversed engineering their way into my project's
sip network. Is there anyway to prevent others from finding out that the
SIP protocol is being used and prevent others to reverse engineer their way
into my sip network?
