<font size=2>My Scenario is to implement Asterisk in a Call center.. I;ve
TE420 Digium card and plan to terminate 4 PRIs (E1) on it. I;ve 30 Agents
inside..Since its a PRI i m not using any hardware echo cancellation
module.The calls would first land on Asterisk and depending on the
options would be transferred to the Agent. I've read lot of opinions on
voip-info.org giving asterisk hardware dimensions. I would like to take a
final call depending on your expert answers :<br>
</font> <br>
<font size=2>Scenario : There would be 120 calls for sure during a 2 hour
period of a day , rest of times it would be serving max. 50 calls. No
matter how many calls come only 30 would be able to talk to agents rest
would be listening to some files on the IVR or be involved in some
polling..This is what the client wants as of now but he needs a scalable
solution depending on traffic..<br>

<font size=2>Queries :<br>

<font size=2>1. For this initial setup Will a Dual processor (Xeon) with
2 Gigs of RAM with TE420 be able to handle the load ? All my agents would
be using the softphones </font></blockquote><br>
This is fine. Even more powerful that what I have used with 240
call legs (call in and extensions out)<br><br>
<blockquote type=cite class=cite cite=""><font size=2>2. What should be
the ideal CPU load that i need to watch - may be if the load average
crosses 6 or 7 - should i worry ?</font></blockquote><br>
Not to worry unless you do a lot of media / codec transcoding. Keep
everything the same at all times.<br><br>
<blockquote type=cite class=cite cite=""><font size=2>3. Even though i m
adviced against AGI scripts (as they eat precious CPU cycles)- they seem
very powerful and i m desperate to use them...Will the above setup get
hampered in any way if i use them ?</font></blockquote><br>
I have used them to answer IVR with up very complex scripting and
interaction. Very little overhead noticed even with 50+ running at
the same time.<br><br>
<blockquote type=cite class=cite cite=""><font size=2>4. Now scalability
- If i want to increase the agents to 50 from 30 and add another PRI -
what are the areas i should focus on - another machine ? or some
additional RAM and processor ?</font></blockquote><br>
I did the opposite. I put 60 astrisk units together in a farm to
handle IVR front end<br>
to 6,000 simultaneous calls. With multiple CPUs, I gained 24*7
dependability<br><br>

<font size=2>I;ve been working all along on Dialogic but want to shift to
Asterisk as it has lot of features and just fits in my needs (PBX + IVR
in 1 box! ). </font></blockquote><br>
Good move! ! ! !<br><br>
