What is the impact of using same server Active Fax on a network? How and where are the files stored until they are read? When they are read, is it like a voice mail that is streamed or is it just like opening a text file across the network? Last question is how large are those files? Thanks in advance. <br><br>
You mean using the Unity server as your fax server as well? The big impact there is rasterizing documents into TIF files (i.e. if you fax email to yourself we need to render the text and qualifying attachments into a TIF file) and the memory hit for the fax server application itself. Theres certainly overhead for the fax processing itself but the fax card handles most of the ugly stuff.
Having the Unity box do everything is really only appropriate to very small installations. Having Exchange, a voice mail server, a fax server, web server, etc all crammed onto one little box is pushing the limits of practicality. A separate, stand alone fax server is really more appropriate. Unity 3.0 will, in fact, no longer be supporting ActiveFax on the same server with Unity. The installation issues, support and overhead have proved to be more than its worth. We will be supporting 3rd party, off box fax capabilities only.
The faxes themselves are stored where the Exchange fax gateway tells them to be (this is the same model most fax servers use, actually). In this case the box you install the fax server on takes the fax and drops it into a folder that the fax gateway is monitoring (usually from another server on the network most fax servers want to be on their own box and not crammed on with Exchange). When the gateway picks up the fax it routes it to the appropriate inbox based on the dialed number or whatever routing criteria the customer has set up. Outbound is the opposite the gateway drops the outbound fax into a folder on the fax server and the server picks it up and faxes it out.
In the case of ActiveFax the inbound and outbound faxes are stored (if memory serves I dont have one in front of me) in \commserver\fax\lfexgateway\in and \out for inbound and outbound faxes. Theyre stored in a proprietary format and theyll only be here long enough for the gateway to pick them up and stuff them in the users mail store in Exchange or to be delivered outbound.
When we offer you a fax over the phone and you elect to delivery it, we forward the fax to the fax gateway (the all work about the same) and that file gets dropped by the gateway into the directory being monitored by the server. Theres no streaming involved here, its just a straight file copy.
If you opt to fax an email to yourself, the email is forwarded to the gateway and its smart enough to run it through a rendering process (it essentially runs it through a printer driver to convert it from its text format into a TIF) and then drops the resulting fax file into the shared directory as well.
Its kind of hard to say how big a fax is depends on how many pages it is and how dense the image is. TIFs are reasonably small, however.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
