Need a bit more detail. The 5120 is kind of a wimpy processor, but what is keeping it busy? What do 'top' and 'htop' show are consuming the processor? What is your application? What are 200 calls doing? Are you calling a bunch of AGIs written in scripting languages? Eliminating translation is difficult. How do you know you were successful? Do 'module show like codec_' and 'module show like format_' show anything unexpected? Below are the further details:top and htop shows that 'asterisk' is consuming the whole cpu power.Application: Kind of SIP trunking - call is coming from IP and using dialplan routed to other third party IPAre you calling a bunch of AGIs written in scripting languages? only one AGI script written in PHP is called with 'h' extension once the call is hungupmodule show like codec_ vm*CLI> module show like codec_ Module Description Use Count codec_a_mu.so A-law and Mulaw direct Coder/Decoder 0 codec_dahdi.so Generic DAHDI Transcoder Codec Translato 0 codec_alaw.so A-law Coder/Decoder 0 codec_lpc10.so LPC10 2.4kbps Coder/Decoder 0 codec_adpcm.so Adaptive Differential PCM Coder/Decoder 0 codec_g722.so ITU G.722-64kbps G722 Transcoder 0 codec_g726.so ITU G.726-32kbps G726 Transcoder 0 codec_ulaw.so mu-Law Coder/Decoder 0 codec_gsm.so GSM Coder/Decoder 0 9 modules loadedmodule show like format_ vm*CLI> module show like format_ Module Description Use Count format_g726.so Raw G.726 (16/24/32/40kbps) data 0 format_ogg_vorbis.so OGG/Vorbis audio 0 format_pcm.so Raw/Sun uLaw/ALaw 8KHz (PCM,PCMA,AU), G. 0 format_g729.so Raw G729 data 0 format_wav.so Microsoft WAV format (8000Hz Signed Line 0 format_wav_gsm.so Microsoft WAV format (Proprietary GSM) 0 format_g723.so G.723.1 Simple Timestamp File Format 0 format_gsm.so Raw GSM data 0 format_vox.so Dialogic VOX (ADPCM) File Format 0 format_mp3.so MP3 format [Any rate but 8000hz mono is 0 10 modules loaded Thank you,Kamlesh -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
