Please log in for more thread options At work we've been contemplating going to a fasx server, and finally the ball is rolling. We are supposed to determine how many fax lines we have thrupout the district, and we thing it's about 150. We have a server and will probably get a bundle pkg with the software. What I'd like to know is what the pros and cons are of going to this system. I've heard that the fax spammers will war dial a server (U. of Washington had this happen) and tie up all the fax lines. Also I'm guessing that a single ISDN PRI (23B + D) will be enough to serve this many lines. We intend to have the incoming faxes come into our Outlook inboxes. We have a number of Xerox Workcentres that can scan a hardcopy in and put it into the fax software to send. I guess we have to make a list of analog fax lines so that SBC can arrange for termination and swing over to the new system. I have some PBX experience but nothing having to do with fax servers. Your good experiences and horror stories will be much appreciated. Thanks. -- @@F@r@o@m@@O@r@a@n@g@e@@C@o@u@n@t@y@,@@C@a@l@,@@w@h@e@r@e@@ ###Got a Question about ELECTRONICS?

Please log in for more thread options The number of incoming fax lines is not really the issue. The issue is going to be the total amount of time all the lines spend sending and receiving faxes. In order to properly size the inbound pipe, you will need a traffic study on all the numbers. This will help you determine the number of total trunks needed to handle the busy hour(s) on the circuits. Each of the inbound fax lines can be assigned to a DID, so a reduction of 30 to 1 or even more is a good starting point. The number of circuits used for outgoing will be the real key, but again, with a fax server faxes can queue so if you take a real shot in the dark and reduce the trunks to a 23B+D you will probably handle the entire load with capacity left over. Most fax machines don't get a lot of use, 60 minutes of traffic in a month would be a fair average for most office faxes. We have a couple in our shop that send 5 or 10 2 - 3 pagers and receive about 10 or 15 two to 3 pagers over a 10 hour period. That still works out around 8 CCS for the entire business day.

I'm happy to find out that a single PRI will probably handle the load. I've received several junk faxes this week on our two machines, mainly pump and dump stock touts. And I've reported them to junkfax.org. Right now most of the fax machines get little use, except for those damn junk faxes. I figure that most machines cost about $20 a month, $15 for the phone line, and the remaining for the cost of the machine and consumables. I'm hoping that when we go to the new server, all the savings in phone line cost, over $2000 a month, will pay for the system quickly. But those damn junk faxes may throw a monkey wrench into the whole plan if they tie up the lines a lot during the day. Scary thought. > Watson A.Name - "Watt Sun, the Dark Remover" wrote:

Yes, the war-dialers will find it and spam-fax you to death. To prevent (or at least thwart) it: First of all, if you don't -need- to send/receive faxes after regular business hours, shut it down. Most of the fax spammers troll for fax servers at night. Secondly, if the fax server software supports it, set the ports to not answer until the 5th ring. If you can deploy both of the above procedures together, you stand about a 99% chance of beating the spammers. >

Thank you for that info. I'll have to ask about those things. \"Watt >
