Hi Liong, Which process is taking the CPU. Please measure and let me know. In case it is the SD card writting you can try enabling the DMA. In package/uClinux-dist/vendors/Rowetel/IP04/pre_config/ip04.c .enable_dma = 0, // if 1 - block!!! modify to 1 Please report the performance difference.

Besides, if I change the mixmonitor path to persistent file system, the loading can also be a bit lowered, but persistent file system doesn't have enough memory for my application. I tried also to do recording on persistent file system, then move the file to SD card on hangup, but other channels are affected when one of the channel hangup (due to high loading when moving files to SD card) Any idea? -- Best regards, Liong Kam Fung On 19/11/2010 16:42, swi...@li... wrote: Liong, forgot to ask about the case G729 is used.

Coz when the loading in high, voice quality become very bad (echo/disconnection/delay occurs) Besides, Dimitar, could you please put dnsmasq into switchfin? cause I finally find out that udhcpd is not good for phone configuration provisioning. (sorry it have been a while I didn't touch the phone provisioning work, since I was so busy on several projects) -- Best regards, Liong Kam Fung ------------------------------------------------------------------------------ Beautiful is writing same markup.
