Hi everybody, I would like to decrease the load of my asterisk server. Could someone recommend me a solution? I have thought about a hardware component that would do some tasks as compression/decompression or codec translations but wonder if such a solution exist. Thanks for any suggestion Lamine
One thing I do is use rawplayer instead of mpg123 for music-on-hold playback, so that mp3's don't have to be decompressed in realtime. See the wiki for details on using sox to convert your audio samples to raw format, and how to configure musiconhold.conf to use rawplayer to play these files. -mike Mamadou Lamine KA wrote:> Hi everybody, > > I would like to decrease the load of my asterisk server.

there was a document somewhere that stated those hardwares had DSP. However I do not use them, so i just read about it a long time ago. Maybe a quick google can shed some light....

It is not that they are not working with Asterisk... It is that there are none available. Go check out the link that was sent to you before... Here it is again.... http://www.zapatatelephony.org/ As you can see, Zapata (which drives Asterisk) was originally designed to be a chipless DSP solution. All the functions of a DSP without the need for specialized equipment. Plain old x86 doing the functions of DSP. So that is why there are no cards with DSP for Asterisk. It was designed to not need them. The fact that new cards are getting DSPs now is just due to the fact that * servers are being loaded so much now that offloading echo cancellation and such to a DSP should allow for higher capacity systems across the board. Of ccourse, being vaporware, we have not even seen if it will be that much of a benefit.

As for digium cards latest cvs commits suggest that there is some ongoing development on hardware based echo cancelation and dtmf detection. So its just a matter of time. rgrds m. _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
