NOOOO!
Unless they are starting with a working application and modifying it, they 
will be exactly one and a half years late for their deadline, and about 
$300,000 short.  Here's what I need you to ask management;
1)      Does the software currently work, but it's in need of tweaking (IE 
the telephony stuff!)
2)      Telephony on the AS/400 exists, and software exists to do almost 
everything you want it to do (and from personal experience, the AS/400 
services 3000 calls a day!)  I would interface the system to almost any 
telephone system using sockets, built into the AS/400!!!
3)      Call Path software (with some minor tweaks) exists that can really 
enhance existing application to interface with the existing calls comming 
in!
4)      40gb of data on a unix system!  If you can partition the system 
enough times, you'll be sick of the unix box really quick (One of the 
fastest databases on the market is DB2/400 and holds the record for the 
largest file (1 Terebyte I recall) and 1 billion records, and takes 30 
minutes to do a rather complex query

So if you want to modernize an AS/400 - teach it new tricks by doing the 
following;
1)      Get a RISC box (They really tear up the pavement!!) A 620 AS/400 
will easily service your environment.  If you multiprocess, you'll get 
enormous leaps in speed!
2)      Use a GUI front end like Jacada (Turns all AS/400 screens into Java 
front ends) or some GUI tool to teach the front end to look better - you 
can also modernize portions of the application!!  This also turns a Green 
screen into something more palatable for the users. Here's a cool thing 
about this - this is about 3 months of work on a complex application - the 
GUI applications does a lot of the work for you!
3)      Get a Sockets front end - about $3000 that will utilize ILE RPG to 
communicate with your telephone system - This is WAY easier then it sounds 
- usually within one compile - I repeat ONE compile!

The Unix solution will require some hidden costs that the vendor is NOT 
telling you about like
1)      Re-training the ENTIRE staff for a new System
2)      Re-training the ENTIRE staff for a new software package (which if 
they use the current system as a framework, all they are doing is 
replaceing the AS/400, or if they are replacing the software with new 
software, 40GB of data takes about 4 days to convert...
3)      How about the fact that you have to BUY all the stuff everyone 
takes for granted on the AS/400.  Like the Database, the Security, SQL and 
other stuff.  So Here's what happens when a UNIX problem happens  - Quick 
call the Operating System Guys...nope it aint the operating system... it's 
the Database they say.  OK Call the Database guys (remember - time is 
ticking right now - and we've already called the wrong people)  So you're 
on the phone with the Database guys - they IMMEDIATLY blame the operating 
system "Hey - we wrote it right, talk to those mean OS guys!"

Are you scared...  Or you can upgrade to RISC (you MUST do a parallel 
upgrade - don't upgrade the current equipment - Get the Faster Disk 
Drives!)  A Server AS/400 FLYS!  The invader boxes (The 170) really move!!! 
 Potentially you'd have more system, less footprint, and it's all done 
within a weekend.  If you're having speed problems, listen to a hardware 
vendor, then skip to the next more powerful box, and possibly save money on 
lease payments!! or Just get a FAST! system.  The Slowest RISC AS/400's is 
about the same speed  as the FASTEST 'F' box ever made...

Think about this!  Please before you make a major mistake!
I've seen the "We're pissed at the <Fill in the midrange equipment>" 
projects go into the hundreds of thousands of dollars, then they buy an 
AS/400 anyway!!!
