For the unfamiliar, ra fax server is a device that receives and routes inbound faxes via email. A basic fax server unit can receive a fax and send it to a pre-defined email address. The more expensive units can route a fax to different email boxes based on the number dialed. This allows different numbers to be assigned to specific individuals or functions (sales, customer support, etc), thus forwarding their faxes to them automatically. This is a very attractive prospect, but until now has almost always required expensive T-1 based phone service with DID numbers to work.
With the 3CX phone system, there is now an inexpensive way to implement a fax server. The 3CX software has fax functionality built-in. Since it can handle VoIP calls without additional hardware, it is easy to get multiple phone numbers issued for little cost. Thus, the sender dials a number specific to the desired recipient, and the fax routes to the associated email box.
The beauty of the 3CX approach is the cost. The basic 3CX software supporting 4 simultaneous calls is $450 plus installation. If you install it on an existing PC or server (which we would not recommend for a full phone system, but if only used for faxing is ok), there are no other hardware or software expenses. Basic VoIP service from nexVortex is $30 a month, and DID numbers are $5 or less per month. The result is a very inexpensive fax server than can route inbound faxes directly to a large number of recipients.
Since faxing over VoIP is still a bit tricky, it is important to use a VoIP carrier that supports T.38, the latest standard, which ensures the best possible fax reliability using packet redundancy.
While the use of faxing is continuing to decline in the face of email, it is still used quite heavily, and is not going away any time soon. If your organization is stuck with a large volume of inbound faxes, 3CX provides an inexpensive approach to automating the handling of them.
