Hey Matt,

What make me choice, or thinking in choose JAVA-AGI so far i know there is a
way of using with a container (jboss or something like that) so the requests
come as an servlet request.

Someone had this kind of env?

Thanks

If you've got anything but trivial AGI loads you should switch to
FastAGI and put your business logic on a separate server to your
Asterisk server. I use a deployment where a call could make up to 3
AGI requests per call before being put through (for things such as
looking up accountcode, checking account credit, setting PSTN
callerid). We monitor the time thw whole process takes and on average
it's less than 100ms on an Asteisk server that peaks at 200
simultaneous calls (400 bridged) and 3 to 5 call set ups per second.
The business logic processing the FastAGI calls is C# and .net which
means Java would be able to handle it easily as well. The most likely
bottleneck under high load will be your database.

Regards,

Greyman.

Hello folks,

Someone just asked the same question on our Asterisk-Java users mailing
list. I posted a small blog entry at http://asterisk-java.org/ about
doing AGI (FastAGI) in a JBoss MBean. I think no matter what language,
it is going to be better to do FastAGI than spawn a new process every
time -- in which case a Java daemon may even be able to outperform more
traditional languages as it optimizes at runtime .

Cheers,

There is really no reason why you cannot.



Personally... I'd avoid using Java for AGI's that you
think are going to receive heavy use... simply because the JVM adds a
lot of overhead, and possibly a very real performance impact from having
the load the JVM everytime. Of course there is overhead as well if you
do PHP instead, as the PHP interpreter has to load everytime... but
that's probably pretty light-weight in comparison to the JVM.



Of course you could compile your Java code to native
binaries to work around that problem, but I have no experience doing
that.



Please keep in mind that I have not actually created or
used any Java AGI's... really just my thoughts without any experience.

Subject: [asterisk-users] AGI asterisk high balance



Hello,



Is there a problem to use AGI JAVA to write an AGI to
billing calls and customer accounts?



Anyone have experience with it could give me some tips?



Thanks,

Well database really is a bottleneck for me. I am currently trying to do
rating stuff in agi using perl. What im doing is i lookup the rate of every
dialed code for every call from the mysql database using the longest match
technique. The longest match technique costs atleast 2-3 mysql queries for
every call untill the dialed code is matched out of 14000 dialcodes. I dont
know how to calculate the exact delay due to execution of agi, but on the
asterisk cli whenever that agi executes, there is a visual delay of about
half a sec to move from the agi extension to the next extension (can anybody
tell me how to calculate the delay).

Now im planning to use the manager api for constant connectivity to mysql
and to enhance the longest match technique. Can anybody help me with this?
Is it a good idea to ue manager api for lookingup the rate of the live
call?

I think his connect/disconnect is going to take far longer than his 3
queries.
The fact that Asterisk doesn't support sustained MySQL connection from
the DialPlan
is in fact quite a big deal that Digium seems to have its head in the
sand about.
And one of those things that SHOULD come up in those "Is * Ready For
Prime Time Threads"
