NetGen Smart ATAs Officially Certified

Posted by Dana Meltzer on Jun 7, 2017 10:27:31 AM

We are pleased to announce that we have successfully completed interoperability testing with NetGen’s Smart ATAs. NetGen Communications, Inc. (NetGen), a spin-off of Commetrex Corporation, is a provider of ATAs with patented Smart FoIP, gateways, IP and wireless/IP PBXs, and IP phones. Their Smart ATAs are equipped with Smart FoIP patented technology that finally makes FoIP calls as reliable as PSTN fax calls. In addition to innovative fax capabilities, the Smart ATAs also provide quality voice performance and a full range of calling features.


NetGen found that serious problems with SIP negotiations for Fax over IP calls exist in the carrier-based networks. Since our SIP trunks were specifically optimized for FoIP, we are the only provider of reliable T.38 FoIP service. This makes us a natural fit with the Smart ATAs and their focus on reliable FoIP performance.


After rigorous testing, our interop ninjas found that the Smart ATA’s excellent T.38 support, combined with our

T38Fax Joins Obihai's List of Compatible Service Providers

Posted by Dana Meltzer on Jun 1, 2017 12:45:04 PM

T38Fax is pleased to join Obihai’s list of compatible service providers. Obihai Technology is a leading manufacturer in the Voice over IP endpoint industry and maker of the best-selling OBi universal voice adapters and IP phones. They developed OBiTALK, a web portal and OBi configuration utility which helps OBi users configure devices and access applications.


Within the OBiTALK portal, Obihai offers a list of compatible service providers, which allows users to easily configure an OBi phone adaptor or IP phone with their specific provider. Using the OBiTALK portal, OBi device owners can select their service provider from this list and enter their credentials. Once a selection is made, the device is automatically configured to work with the service provider, and calls can be made and received within minutes. 


Service provider partners can also sign in to the OBiTALK ITSP Device Management Portal (DMP). This tool was designed for service providers, system integrators, and value-added resellers (VAR) to manage their OBi device deployments. It allows them to remotely and securely access and configure OBi devices from anywhere. When a service provider signs in to the OBiTALK portal, they can set up SIP registration and configure more advanced VoIP functions. This will eliminate the need to configure and re-package each device before sending it to the end user.


T38Fax is proud to be the only FoIP-specific service provider on the OBiTALK compatible service provider list. Our SIP trunks were designed by fax industry experts to solely offer T.38 Fax over IP call origination and termination. We have tested our integration in the OBiTALK portal and found that it offers an easy and straightforward way to

T38Fax - The FoIP Solution for Any Use Case Scenario

Posted by Dana Meltzer on May 18, 2017 11:25:46 AM

If you're reading this blog, then you rely on FoIP in some way, and it's likely causing you headaches. Maybe you're a single ATA user trying to fax with your current carrier, but not having much luck. Perhaps you have a fax server that won't work consistently now that you've upgraded your phone network to VoIP. Or you're a service provider that can't seem to provide reliable FoIP to your customers and fax support is causing you nightmares.


If you fit into any of these categories, then your business depends on FoIP, but you can't get it to work reliably. As you upgrade your communications infrastructure to SIP, fax support can get left behind. Finding a carrier that guarantees (and supports!!) T.38 on your service is almost impossible. If you’re a carrier or service provider, you know that successful T.38 requires significant investment in equipment and expertise and fax troubleshooting takes skill from seasoned fax experts.


Luckily, we can help! T38Fax provides reliable faxing and premium support over our SIP trunks, which were specifically designed for T.38. Whether you’re a single fax user, a business with a fax server or IP-PBX, or a hosted VoIP or SIP trunk vendor, our Power-T.38 service can work for you. Find your use-case scenario below and see how.

Asterisk Officially Certified

Posted by Dana Meltzer on May 11, 2017 11:48:34 AM

We are pleased to announce that we have successfully completed interoperability testing with Asterisk. Asterisk is a free and open source framework for building communications applications, like business phone systems, call distributors, VoIP gateways, and conference bridges. As open source software, it has been enhanced and tested by a global community of thousands. It is sponsored by Digium, and it is used by almost the entire Fortune 1000 list of customers.


Some of our largest service providers have built their businesses on Asterisk and related open source telephony tools.

Simply activate service with us, connect to our SIP trunk, and marvel at how well the faxing works.


Our interop ninjas have been hard at work interop testing Asterisk. Their software has passed our rigorous testing requirements and made it to our Approved List. We've gathered our screen shots and recommended best practices and assembled them into our Asterisk knowledge base article, which you can find here:

Posted by Dana Meltzer on May 2, 2017 9:54:13 AM

T38Fax is pleased to announce the launch of its new customer self-care portal. The portal has been completely redesigned as part of our ongoing commitment to enhance our customers' experience and provide outstanding support. We wanted the portal to be more intuitive, sleek, and user-friendly, and we also needed a modern foundation upon which to begin adding new features such as DID ordering, LNP porting and self-service trunk creation. Look for these new features to begin appearing in the coming months!

The new portal launch follows the release of a preview that was sent to customers for feedback. We incorporated many customer suggestions and in the end we think you will agree that the new self-service website offers our customers a far superior online environment, with enhanced features and functionality.

Cisco SPA112 and SPA122 ATAs Officially Certified

Posted by Dana Meltzer on Apr 3, 2017 11:00:00 AM

T38Fax is pleased to announce that we have successfully completed interop testing with the Cisco SPA112 2-Port Phone Adapter and the Cisco SPA122 ATA with Router. We're especially excited about this certification since many of the service providers we speak to on a daily basis have already standardized on this platform and have large preexisting deployments of these devices in the field. The device's T.38 support is excellent, but like all T.38 devices they're only as good as the service they're connected to. That's where we come in (see below for links to our knowledge base articles)! 


Cisco itself doesn't need much of an introduction, of course. These ATA’s are part of Cisco’s line of best-in-class small business voice gateways and ATAs, designed to support office or residential communication needs. The undrlying technology has a strong pedigree in the SIP industry, having started out in the early days as Sipura Technology, which was wisely acquired by Cisco and branded as Linksys, then eventually promoted to the official Cisco brand. They are compatible with all industry voice and data standards and common telephone features such as caller ID, call waiting, and voice mail. Fortunately, the Cisco adapters also have a very mature T.38 stack, an essential feature to ensure reliable faxing over SIP trunks.


Most VoIP service providers struggle to provide a stable, reliable solution for fax. Our Power-T.38 SIP trunks, combined with Cisco's ATAs are a powerful solution to this problem, and in our experience result in happy

Service Provider T.38 Offload - We Want Your FoIP!

Posted by Dana Meltzer on Mar 29, 2017 10:01:20 AM

If you've found this article there's a good chance you're a hosted VoIP or SIP trunk vendor whose customers are trying to send faxes, unsuccessfully, over your network. Perhaps your support team is demoralized by the constant barrage of cases being opened by customers who found out just a little too late that VoIP and fax don't play nicely together? Do you wish you could offer T.38 FoIP that actually worked, without the technical support burden? Do you have customers that are frustrated by your lack of fax support? Are you afraid those customers will take all of their business to a competitor who not only advertises support for T.38 but who can actually deliver the goods?


What if I said this could be you? And that after one of the easiest configuration changes you've ever experienced, you'd never have to worry about fax again. Sound too good to be true? It's not.
