India is a Spamming Hub

Wonder where all those annoying spam messages come from? Who sends them? Well, you have got some answers here. Panda Security, a player in antivirus and preventive technologies segment, has stated in its report that India is the world's number two spammer. Surprised? Even we were.

Panda Security has released a report stating that Brazil, India, Korea, Vietnam and U.S. head the list of countries from which most spam was sent during the first two months of the year 2010. With respect to the cities from which spam was being sent, Seoul was first in the list, followed by Hanoi, New Delhi, Bogota, Sao Paulo and Mumbai.

The five million emails analyzed by PandaLabs came from a total of almost one million different IP addresses. This shows that the spam is mostly sent from zombie computers belonging to a botnet. This way, the computers of the infected users themselves are those which send the spam. The cybercrooks have thousands of computers at their disposal, which do the dirty work for them.

Spam is nothing but a business and is used primarily either to distribute malware or sell/advertise all type of products. Therefore, as long as there are users, no matter if they are few, who trust these messages, it's enough to continue betting on it.

Why You Need SIP Protocol For Voice Communications

Session Initiation Protocol (SIP) is the transport technology for person-to-person real time traffic over the Web. Its defining specifications come from the SIP working group of the Internet Engineering Task Force. SIP provides access to the public switched telephone network for voice data at 3 kHz bandwidth and common number dialing using Voice over IP (VoIP). It can also be expanded to handle IP telephony combined with video and instant messaging. Future improvements will allow SIP applications such as video conference calls, application sharing, home monitoring, and interactive gaming.

SIP is in most cases thought of as a method to implement the functionality of common telephony over an IP network. It is replacing the older, less versatile protocols used in the old days such as H.323 and MGCP. These older protocols functioned at a very low level to connect IP phones to the public telephone network. SIP, on the other hand, provides a sophisticated and straightforward way to network the enterprise. For instance, SIP uses email addresses as the SIP address instead of a telephone number over the standard phone network.

Suppliers of SIP components are quickly developing innovative products and software to get the upper hand in this new Internet communications method. SIP telephones, PC client software, SIP servers, routers, and firewalls are now obtainable from companies such as Ingate Systems and Cisco.

Prior to implementing a SIP solution in your company, you should consider the proper configuration of your corporate firewall to accept SIP. Many of the typical firewalls already installed in business offices are not designed to allow the SIP protocol. First, SIP media streams are transferred over dynamically allocated UDP ports that are often closed on firewalls. Second, SIP clients within a firewall can not be accessed using IP addresses because these addresses are local and unique to the LAN. Third, you need to ensure that either your T1 line carrier or Metro fiber service is able to support the SIP protocol from your internal network to the outside world. Your IT manager will need to evaluate how to correctly support SIP to overcome these technical problems. By including a SIP proxy and registrar for managing the firewall, it is feasible to deal with complex SIP scenarios for reliable and confidential communications.


SIP trunking brings a number of perks to the business user such as cost savings, networking flexibility, and emergency disaster recovery. It can eliminate the high subscription costs of basic rate interfaces and primary rate interfaces. It also optimizes the bandwidth usage by providing both voice and data over the very same connection. Businesses will have the flexibility to route calls to preferred carriers and the redundancy of using several service providers.

How to Explain SIP to a Non-Technical Person

SIP... or Session Internet Protocol... isn't necessarily a new communications concept. It has been around awhile although it seems to be garnering a resurgence in Telephony applications today. But... how do you explain what SIP is when asked?

Good luck with this one, trying to explain SIP to technical people is tough enough.

Here's some very simple short statements that may help...

- SIP enables telephony over the internet network

- SIP allows us to packetize and prioritize voice traffic over digital circuits.

- SIP is a way voice is packed into a digital signal that is then enabled for transfer through the internet.

- SIP digs a channel in an IP network so voice/video can flow between two (or more) places. When you finish talking, SIP shuts the channel up.

- It's an internet protocol like HTTP for web browsing, only this one is used to make a phone-like connection between computers, pda, voip-phones or other devices that can talk over the internet.

- SIP is a protocol that allows unlike mediums to communicate. All you really need to know is that SIP is the new PRI and is more cost effective from a trunking perspective.

- SIP has nothing to do with the internet.... regardless of where, when, or how voice traffic is being transmitted. f it's being sent as 0's and 1's... SIP is what differentiates voice from all other data.

- SIP enables you to eliminate the cost of maintaining two networks (POTS + Ethernet) by putting your phone traffic on your Ethernet network.

- SIP is a business-class, integrated voice and data service with connectivity provided to your IP-PBX (a telephone switch that supports voice over IP)

Or... you may explain to a non-technical person by describing the SIP VoIP operation like this:

1. Callers and callees are identified by SIP addresses.

2. When making a SIP call, a caller first locates the appropriate server and then sends a SIP request. (The most common SIP operation is the invitation).

3. SIP or VoIP is a technology that allows you to make calls between devices, be it over the local network or over the Internet (Managed or un-managed). SIP is a standards based technology that behaves very much like your old telephone line but just uses the Internet as its medium.

4. Instead of directly reaching the intended callee, a SIP request may be redirected or may trigger a chain of new SIP requests by proxies.

5. Users can register their location(s) with SIP servers.

6. SIP messages can be transmitted either over TCP or UDP

7. SIP messages are text based and use the ISO 10646 character set in UTF-8 encoding.

8. Lines must be terminated with CRLF.

9. Much of the message syntax and header field are similar to HTTP.

10. Messages can be request messages or response messages.

Microsoft, Citrix Offer To 'Rescue' VMware Customers

Microsoft and VMware have been engaged in a snippy back-and-forth over virtualization  for the past couple of years, and a new Microsoft-Citrix joint promotion is further inflaming partisan passions on the issue.

Last week, Microsoft and Citrix unveiled their "Rescue for VMware VDI" promotion, which lets customers trade in their VMware View software licenses for the same number of Microsoft VDI Standard Suite subscription and Citrix XenDesktop VDI Edition annual licenses, free of charge. The promotion, which runs through the end of the year, is open to Microsoft customers with Core Cal or E-Cal with Software Assurance.

VMware has been using View, its desktop virtualization software, to sell its server virtualization technology, but some customers haven't been able to deploy it successfully, according to Sumit Dhawan, vice president for Citrix XenDesktop at Citrix. The "rescue campaign" gives customers a way out and underscores the maturity of the Microsoft-Citrix desktop virtualization offering, he said.

Microsoft Speeds Desktop Virtualization Protocol

Microsoft, trying to gain a larger footprint in desktop virtualization, has applied a protocol acceleration technique to its lagging remote user protocol, RDP, and is widening its partnership with Citrix Systems.

The desktop acceleration technology was acquired from Calista in 2008 and is now called RemoteFX into Microsoft Remote Desktop Services, its former terminal services.

Remote Desktop Services includes the RDP protocol, which feeds the desktop display to either a terminal, or more frequently today, a virtualized desktop device, such as a laptop or thin client. RemoteFX will act as an accelerator for RDP but it will do so only for the clients of a server running Windows 7 Service Pack 1 server.

Microsoft Sued Again After Infringement Verdict

It may seem like a déjà vu situation to Microsoft's legal team. The software giant lost an important patent infringement lawsuit on Tuesday, but the winning parties aren't satisfied yet.

So on Wednesday, the plaintiff -- a small holding company called VirnetX from Scotts Valley, Calif. -- sued Microsoft (NASDAQ: MSFT) again, for the same infringement. However, this time VirnetX is going after Microsoft for using the infringed patents in Windows 7 and Windows Server 2008, according to the plaintiff's filing in the new case.
