[asterisk-users] New implementation asterisk

[Edwin Blommaerts]

This sounds a bit suspect. What sound files are you talking about?
Voicemail? Prompts? Responses? Dictation?

        Phone call recordings, outgoing and incoming to and from the call center.

That explanation sounds bogus. Where are you seeing segmentation errors?
What processes are faulting? Do you see the same thing if you restart Asterisk or MySQL?
In a production environment, 'seg-faulting' is unacceptable and needs to be resolved.

        Indeed, that's why I'm opting for a fresh install and this time setting it up in the right way.

) What does the system do?

        It is supposed to record the calls of the call agents there is about 10 - 15 call agents. The reason for storing them is that a third party should be able to retrieve them through our corporate website. I don't understand why it     is necessary to store these files into a database? To me this is not needed at all and would GREATLY improve performance if we just used a path to the files stored into the database.

) What version of Asterisk?

        1.8

) What channel technologies are used?

         I will have to get back to you on this, I'm not exactly sure.

) Average simultaneous calls?

        8 * 5 mins

) Peak simultaneous calls?

        15 * 5 mins

Thanks for the quick reply

You have provided no details to base suggestions on, so take any suggestions with a grain of 'salt.'

In a production environment, 'seg-faulting' is unacceptable and needs to be resolved.

In some environments, 3 seconds might as well be never. I'd aim for sub-second response for anything that affects call processing.

Does this happen with every call?

What does the console log (with debug and verbose cranked up) look like when this happens?

With no details, this comes down to personal preference.

For 'big systems,' I like to 'front-end' a pool of Asterisk servers with a couple of boxes running OpenSIPS and I like to run databases on boxes by themselves.

OpenSIPS lets you load balance and take boxes out of production easily.

I think of database servers and 'telephony servers' as having different characteristics and needs.

If you would like more concrete suggestions, please reply with more details.

Basic details like:

) What does the system do?

) What version of Asterisk?

) What channel technologies are used?

) Average simultaneous calls?

) Peak simultaneous calls?

may shed light on an appropriate solution.
