2. – You can either take your ATA (voip modem) with you, or a mini-version that the voip company probably sells.
Your phone number is connected to the ATA / voip modem, not your ISP or anything else.
The rest… either I don’t know or it’s a matter of where you live.
While I’m here –
Download a few anti-virus and anti-spyware programs, oh and a firewall.
( Avg antivirus – http://free.grisoft.com/ , Adaware anti-adware – http://www.lavasoftusa.com/software/adaware/ , Spywareblaster antispyware – http://www.javacoolsoftware.com/spywareblaster.html , Zonealarm firewall – http://www.zonelabs.com/store/content/company/products/znalm/freeDownload.jsp )
It’s almost guaranteed you got some nasties through either just using Internet Explorer, or downloading stuff you shouldn’t.
Internet Explorer is big, slow, insecure (you’re almost guaranteed to have some viruses and spyware right now), very out of date, and not customizable.
Drop Internet Explorer from use and get Firefox – sleek, fast, safe, easy to use, up to date, extremely customizable… and it has a cool icon.
( Firefox web browser – http://getfirefox.com/ )
Firefox has pop-up blocking built in, and with just one add-on you’ll rarely see another banner ad!
(Firefox adblocking add-on – http://adblockplus.org/ )
Install the programs and scan your computer. You might want to stay offline for this – you’re not protected until AFTER you do it.
After that – password protect your computer account. If you use a wireless connection see if you can get it secured (passwords and encryption)
Make sure to update your virus and spyware scanners once a week, and check for updates to your firewall… and operating system.

Hacking Voip $27.36 Voice Over Internet Protocol (VoIP) networks, the technology used to place phone calls through the Internet, suffer from the same security holes as standard IP networks, as well as new threats specific to telephony. In addition to attacks on network availability and authentication, administrators must contend with eavesdropping, audio injection, Caller ID spoofing, VoIP phishing, and other unique exploits. All of these security holes can result in the leakage of information and in unreliable phone calls. Hacking VoIP reviews the many possible VoIP attacks, and discusses the best defenses against them for both enterprise and home VoIP solutions. Author Himanshu Dwivedi introduces popular security assessment tools, describes the inherent vulnerabilities of common hardware and software packages, and provides the first ever VoIP security audit program. The book covers common enterprise VoIP protocols such as SIP and RTP as well as unique protocols like H.323 and IAX. |

Switching to Voip $26.36 More and more businesses today have their receive phone service through Internet instead of local phone company lines. Many businesses are also using their internal local and wide-area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and it’s revolutionizing the world of telecommunications by slashing costs and empowering users. The technology of families driving this convergence is called VoIP, or Voice over IP. VoIP has advanced Internet-based telephony to a viable solution, piquing the interest of companies small and large. The primary reason for migrating to VoIP is cost, as it equalizes the costs of long distance calls, local calls, and e-mails to fractions of a penny per use. But the real enterprise turn-on is how VoIP empowers businesses to mold and customize telecom and datacom solutions using a single, cohesive networking platform. These business drivers are so compelling that legacy telephony is going the way of the dinosaur, yielding to Voice over IP as the dominant enterprise communications paradigm. Developed from real-world experience by a senior developer, O’Reilly’s Switching to VoIP provides solutions for the most common VoIP migration challenges. So if you’re a network professional who is migrating from a traditional telephony system to a modern, feature-rich network, this book is a must-have. You’ll discover the strengths and weaknesses of circuit-switched and packet-switched networks, how VoIP systems impact network infrastructure, as well as solutions for common challenges involved with IP voice migrations. Among the challenges discussed andprojects presented: building a softPBX configuring IP phones ensuring quality of service scalability standards-compliance topological considerations coordinating a complete system ?switchover? migrating applications like voicemail and directory services retro-interfacing to traditional telephony supporting mobile users security and survivability dealing with the challenges of NAT To help you grasp the core principles at work, Switching to VoIP uses a combination of strategy and hands-on how-to that introduce VoIP routers and media gateways, various makes of IP telephone equipment, legacy analog phones, IPTables and Linux firewalls, and the Asterisk open source PBX software by Digium. You’ll learn how to build an IP-based or legacy-compatible phone system and voicemail system complete with e-mail integration while becoming familiar with VoIP protocols and devices. Switching to VoIP remains vendor-neutral and advocates standards, not brands. Some of the standards explored include: SIP H.323, SCCP, and IAX Voice codecs 802.3af Type of Service, IP precedence, DiffServ, and RSVP 802.1a/b/g WLAN If VoIP has your attention, like so many others, then Switching to VoIP will help you build your own system, instal |
