Understanding Cisco Unified Communications Manager Express Security – Voice Encryption

Voice over IP (VoIP) is not just need of hour for most enterprises; it’s something their business depends on to a degree that without IP communications in place, their business processes and revenue streams will fall apart. In such case, it goes without saying; security of voice networks is one of the chief concerns when it comes to security of intellectual capital and customer data. More often than not, one of the first thoughts is how to secure the VoIP network itself which is leveraged by IP Telephony / Unified Communication (UC) applications.

So what is that may be the most commonly sought after yet elusive security control which plays an indispensable role in securing a VoIP network? Your guess is as good as mine, it is encryption!
