In financial
institutions and other industries where there are strict regulatory
controls to ensure the privacy of customer information, a continued
lack of emphasis on VoIP security will eventually leave organizations
open to legal risks.VoIPshield Systems publishes whitepaper .

IP Telephony Adoption Reaches Mainstream |
|
Monday, 10 December 2007 |
|
Despite some lingering market perceptions to the contrary, IP communications is indeed a mature technology in the midst of broad industry adoption. In fact, the IDG Research Services survey reports that 50 percent of respondents already have IP PBXs installed today and that 63 percent indicate that the technology will be part of their telephony infrastructure within the next 12 months. Check it out here Adoption reaches Mainstream.

Emergency Call Handling in VoIP Networks |
|
Tuesday, 27 November 2007 |
|
Emergency Call Handling (ECH) is an essential feature of today's public
telephone networks, and if Voice over IP based PSTN replacement is to
become a reality, the new technology will have to deliver reliable
handling of emergency calls. The needs of ECH have been extended as a
result of recent national emergencies, such as floods and terrorist
atrocities. These have focused Governments' attention on the need to
secure the lines of communication for key workers and facilities, as
well as support for emergency calls. Check it out at Call Handling in VoIP Networks

VoIP Security is becoming ever more important as high profile fraud
cases hit the press. Strong authentication of users helps mitigate
these attacks, a fact recognised by 3GPP in the IMS security framework.
But 'VoIP over IPsec' poses problems in wireline networks when it
encounters NATs. This paper examines the problems when IPsec meets NAT
and looks at TISPANs solution to the problem. Check it out at IPsec in VoIP Networks

Discussing VoIP Bandwidth |
|
Tuesday, 27 November 2007 |
|
Published by WestBay Engineers Ltd, there are many factors involved when calculating the bandwidth required through a
network. This white paper aims to
explain these factors, and to offer a simple means of making such calculations. It
starts with a basic 'rule of thumb', and then expands this to take specific voice coding
algorithms into account.

|
Discussing VoIP Protocols |
|
Tuesday, 27 November 2007 |
|
Published by Westbay Engineers Ltd., this white paper describes the protocols
which are typically involved when transporting voice over an IP based network. A
basic understanding of the protocols is required in order to understand the bandwidth
overhead of voice over IP and the Quality of Service issues surrounding the technology.
