[asterisk-users] How Secure Is Asterisk

[Sam Tam]

VPN IP phone?
Then firewall up the asterisk to disable any outside access and place the
vpn server with the asterisk in a locked cabinet .

Sure that will stop someone trying to physically listen to their call.
Or they can always use the good old landline or mobile phone and let the
government listen to them too/

Subject: [asterisk-users] How Secure Is Asterisk

I am sure this has been discussed prior, however, I am sitting here and
being asked this very question by my superiors.  They are loving what I have
done with our two Asterisk servers here; however, they keep asking me if it
is secure or not.  Of course, as with anything, I suspect that on a secure
network they can be reasonably safe.  However, realistically if I am using
the asterisk server to make internal calls and discussion very private
matters, how possible is it for someone to listen to calls?  How good is the
encryption if any over an IAX trunk?
