A relatively recent research material stated that the move from old switcher phone boards to digital telephony through internet networks is more of a security risk. This is because, despite the reliability and speed of
digital internet access, adjustments to its security functions and features are still not yet fully tweaked for maximum security regarding telephony. This is perhaps a statement that would send those VoIP investors a good run for their money!
You see, internet service providers know of the security risks involving telephony behind internet access. This is mainly because of past hacker attacks to various internet networks. If this could not be substantially solved despite the claims of most internet service providers of foolproof security measures, then what more could the security risks of
internet telephony hold for the people? Wouldn't eavesdroppers have easier access to such private phone conversations because we have known from the past that these hackers could easily get in an internet network? Thus, I highly suggest you carefully study the standard security measures of your internet network which would house your VoIP capabilities before opting for VoIP instead of conventional telephony. After all, if there's something which people highly regard, it would have to be security and privacy.
