Myth:
IP-based systems cannot be kept secure from threats.
False.
Network managers already have the burden of providing security for the servers,
computers, and other devices on the LAN and WAN. Keeping intruders or unauthorized
internal personnel out of critical systems is done the same way for network-based phone
systems as it is for email and database servers. In fact, when a legacy PBX and its voice
applications are on a separate network from the data network, there are two networks
to guard and monitor. The PBX still has to be defended against the usual attacks like toll
fraud, call redirection, and social engineering of account codes. A properly designed
network, in which any access from the outside is secured by firewalls and controlled by
VPN connections, is needed. A complete understanding of the Telenium
IP
system will
enable the network manager to maintain the system securely.
Myth:
Voice quality will be lower on a VOIP system.
False.
The first wave of IP telephony solutions released several years ago suffered from voice
quality problems. The technology used to convert spoken voice sound to network signals
has been dramatically improved. A network designed to support voice, in which
problems like jitter and congestion are minimized, and voice traffic can be prioritized,
will provide a high-quality user experience. Telenium
IP
systems provide a voice quality
experience equal to traditional digital PBXs when the network is well-managed and
prioritized.
