Urgent: Inbound Queue issues with GFI FaxMaker12

We have FaxMaker installed on a separate system than Exchange 2003. We have verified the SMTP correctors are set up correctly. As we receive faxes, our inbound queue grows. The inbound transfer thread is very slow, only processing one item per 20-30 seconds.  While the inbound items process, our outbound queue does nothing.

I'm aware that FaxMaker is a 16-bit app, and that limits it, but this seems much too slow. We do fax approximately 2000 items per day, and receive another 2000 as well.

Thanks

In such situations, I have configured a few modems as outbound only and a few as inbound only.  By configuring a few modems for outbound only, they will not be occupied with inbound FAXes and so should be available to send FAXes as needed because they ignore the inbound work queue.  Since your inbound/outbound ratio is about equal, I'd assign 50% of you communications channels to each duty.

It depends on what you consider a 'day' when determining your FAX volume, but with a volume of 2000 in each direction, per eight-hour day, that works out to 4+ FAXes per minute in each direction.  Allowing 1 minute for transmission/reception of a 1 page FAX, that would mean you have at least 8 modems.  That of course doesn't account for retransmission attempts, etc.  If it were me, I would assign grouping based on which direction was more important to the business process.  If inbound FAXes are more important to keep staff working during the day, then I'd assign 5 modems to inbound duty and 3 to outbound on the assumption that the outbound FAXes can arrive during the off hours.  That math changes if you use a 24 hour day.

HTH!

We have 13 lines for outgoing and 8 lines for incoming set aside specifically for these purposes. I forgot to include that! Thanks for mentioning it and reminding me.

In that case, I'd talk with GFI about the issue or hopefully someone else has some input.  The servers I work with have fewer ports but I've never seen processing in the incoming queue delay the outgoing FAXes.

Good luck!
