As a rule, IT admins are a wary lot. When a new system is installed into an IP network, the IT group often takes a “worst possible scenario” view of what this system could do to their network, and to everything else that’s on it as well. You can’t blame them; with IP networks often in the news for negative reasons such as security breaches and system failures, IT groups are under increasing pressure to ensure their networks run smoothly, quickly and reliably. Anything new that drops into their network needs to be scrutinized for possible failures.
A FoIP (fax-over-IP) solution powered by Biscom’s FAXCOM fax server solution in conjunction with the Dialogic SR140 FoIP software license will run smoothly in any IP network. Using the T.38 protocol, which was implemented specifically for real-time transmission of faxes over IP network, provides for seamless integration into a network. The bandwidth savings by using T.38 (rather than G.711 “pass through”) provide for negligible-to-no impact on how an IP network runs. The SR140 license will do IP signaling via one of two tried-and-true IP call control protocols: SIP, or H.323, both of which have been around for many years. As long as the IP ports that these protocols use are allowed by the IT group to communicate in an IP network–1720 for H.323 and 5060 for SIP–the IP call setups will flow quickly and easily. The IP ports used by the T.38 packets, typically in a higher port range such as 56000-57000, can be adjusted so they won’t conflict with any other ports being used in the network. Putting the T.38 FoIP traffic on its own VLAN further helps ensure that conflicts won’t occur–and that a high quality of service will be implemented.
As far as any concerns the fax server will crash, virtualization will help with this. As the FAXCOM/SR140 solution is entirely software, you can put the solution on a virtual machine, as many of our FoIP customers do today and have done–successfully–for years. Taking a “snapshot” of this virtual machine so that it can be quickly reloaded should anything happen to it or its host, will help ensure a quick and virtually seamless re-implementation of your mission critical FAXCOM fax server. Additionally, users of VMWare to virtualize their machines can take advantages of the features of vMotion to further safeguard their investment in a software-based FAXCOM server.
So, if you’re considering a FoIP-based fax solution, you can rest easy in knowing that Biscom’s solid FAXCOM software solution, built on Dialogic’s equally solid SR140 FoIP license, will work in your IP network in exactly the manner that your IT group will love–once it’s up, it’ll run so well that they won’t even know it’s there! And to the IT group, that’s a good thing.
