<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I just want to clarify a few things.
I have about 100 Toshiba digital phones, 4 ports on the voicemail, and 24 phone
lines. Not all of the lines are POTS lines. I think 8 of the lines
are Direct Inbound Dial (DID). Due to a decrease in call volume, I am
most likely going to cancel 6 – 8 POTS lines in the near future. Also,
due to the cost involved with implementing a completely new phone system the
Toshiba phone system will have to stay. This will be phase out a little
at a time. If the rumor is correct, what would you do if you need more
than four Digium cards? Would you run multiple Asterisk boxes?
Currently, I have Asterisk installed on a Slackware 10 system for testing purposes.
I am going to test it on the side. Once I feel confident with Linux
(sorry, I don’t have a lot of experience with it) and Asterisk, I will
put it in place of the Toshiba voicemail for “live” (after hours)
testing. Luckily, our developer at work prefers running Linux, so I have
someone to run to for assistance.</span></font></p>

<p class=MsoNormal style='margin-left:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>I currently have a Toshiba Strata
DK424 with a Stratagy voicemail system (4 ports). I am looking to go from
having a receptionist answering the phone to an automated attendant. It
appears that Asterisk can be the solution, but I have some questions. Do
I just replace the Stratagy with the Asterisk or do I need to reconfigure the
routing of the phone lines? Currently, the POTS lines come in to the Strata
phone system. Would I need to have the POTS lines come in to the Asterisk
then connect the Strata to the Asterisk? The Strata is equipped with an
automated attendant, but only having 4 ports causes dropped calls. At the
current time, we just want to use the automated attendant and voicemail
features, but we intend to start using VoIP and SIP. Finally, which cards
do I need to purchase? I am not familiar with all the terminology, so I
am a little confused with FXS and FXO. Once I figure out where things
need to go, I think it would make things a little easier. All our phone
lines come in on POTS lines, but we may change to PRI at some point. I
understand that this will change which cards I need. I have mainly been
looking at the Digium cards do to pricing. The Intel (Dialogic) cards
seem to be a lot more expensive. Are the Intel’s any better than
the Digium? Any assistance would be greatly appreciated.</span></font></p>
