What is PRI’s most significant downside?

With the growth of VoIP telephony and SIP trunking systems that provide telecommunications services over the Internet, PRI phone service is often seen as a technology that is in decline. Yet many enterprises have invested heavily in PRI systems and are reluctant to abandon these investments completely, which is led to the presence of many hybrid systems in enterprise telephony.
