Commetrex’ CEO, Mike Coffee, recently noted in his blog that it is often the little guy who is chastized when something doesn’t work, when, in fact, it’s the big guy who’s at fault. And, the world of FoIP interop problems is no different. This time, however, the culprits are clear.<\/p>\n
<\/p>\n
So, check out Mike’s Musings to learn “the Rest of the Story”.[\/vc_column_text][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”grid” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” el_class=”newsletter_inner_page” css=”.vc_custom_1578991890670{padding-top: 70px !important;padding-bottom: 70px !important;}” z_index=””][vc_column el_class=”newsletter_inner_page_bg”][vc_column_text]<\/p>\n

Due to SIP trunking and carrier support of T.38, FoIP is emerging from the enterprise and extending out to the service provider. But, as with the adoption of any new technology, there are technical challenges. Commetrex happens to be at the center of the emergence of FoIP. And, the result, \u201cWe Make FoIP Work!\u201d<\/p>\n
<\/p>\n
So, if you have any FoIP project, product, or deployment, and you have any questions about this technology, come see us at ITEXPO East 2011, booth #528. The conference and exhibition will be at the Miami Beach Convention Center February 2-4. TMC says that registration is up 30-percent over last year, and there\u2019s a strong exhibitor line-up.<\/p>\n
<\/p>\n
And, while you are there, be sure to check-out Mike Coffee, Commetrex\u2019 CEO, as he delivers his \u201cState of FoIP\u201d presentation at Ingate\u2019s SIP Trunking-UC Summit. The session begins at 11:00 on February 3. If you have any FoIP deployments, or may in the future, this is one session you won\u2019t want to miss! So, register, make your travel plans, and come see and hear us in Miami Beach.<\/p>\n

It\u2019s a question that comes from the surging rate of FoIP deployments, and we should know as Commetrex is at ground zero of fax-technology development and deployment. Because of this rapid increase, FoIP-related products and services are being implemented by organizations that have little FoIP experience, so there will be challenges, which is the reason for the question coming up. The legacy carriers are especially in uncharted waters. But the answer depends on whose technology and network you\u2019re using. If your fax-technology source is Commetrex, you have the best there is. But the industry is still on a very steep FoIP learning curve, so you and your customers may need some help, such as Commetrex\u2019 FaxTap for T.38 and FaxTap for PCM. These products will either take a Wireshark capture or PCM recording of a fax session, render the image, if possible, and tell you in a synopsis just what happened during the session.<\/p>\n
<\/p>\n
A Shanghai-based company recently licensed FaxTap for T.38 for use in a lawful-intercept (LI) application. Each LI system shipped includes FaxTap to decode and render the image in fax transactions.<\/p>\n
<\/p>\n
And, there\u2019s more where FaxTap came from: FaxTap is based on Commetrex\u2019 PortableT30, our Fax Modem Bundle, and T.38 protocol engine. Each of these licensed technologies. allow you to bring your server, gateway, or test equipment to market in months, rather than years, and do it at the absolute minimum investment. What\u2019s more\u2026it works, after all we\u2019ve now been at it for 20 years, so we\u2019ve figured a few things out.<\/p>\n

We recently installed a new firewall, but left our old one up during the switchover. Unbeknown to us, the old one had a hole open for our IP PBX and some hacker found it. Not good. We came in one morning to find that our phone system couldn\u2019t make calls. It took a few hours, but after checking everything else, we found that the PBX was being flooded with SIP Invites. They weren\u2019t being accepted because they couldn\u2019t get authenticated, but the frequency of he Invites was overloading the server, making it unable to do anything else.<\/p>\n
<\/p>\n
We traced the attacker to an ITSP in Sheffield England, and the software being used to SIPvicious since it can be identified by the user-agent field in the SIP headers of \u201cfriendly scanner.\u201d Friendly, my eye.<\/p>\n
<\/p>\n
Here\u2019s some of the SIPvicious tutorial on the Web:<\/p>\n
<\/p>\n
\u201cIn order to hack SIP-based phone systems to make free calls, use the SIPvicious suite of tools which allow for easy \u201cauditing\u201d of SIP-based VoIP systems. First use Svmap to scan an IP range to find an available target. Once the scanner finds a couple of these, use Svwar to connect to these proxies and identify the ones that have been configured to not require authentication. Then, use X-Lite, a free softphone to make international calls using this vulnerable SIP proxy. Enjoy!\u201d<\/p><\/blockquote>\n

The good news is\u2026no permanent damage done other than several wasted hours of one of our top guys. The moral of the story is\u2026it pays to be alert. Don\u2019t let it happen to you.[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"
