Hello, I have used the following config_site.h on a Raspberry 1 (ARM as well). During a call, CPU is at 25%. --- config_site.h: # undef PJ_OS_HAS_CHECK_STACK # define PJ_OS_HAS_CHECK_STACK 0 # define PJ_LOG_MAX_LEVEL 5 # define PJ_ENABLE_EXTRA_CHECK 0 # define PJ_HAS_ERROR_STRING 0 # undef PJ_IOQUEUE_MAX_HANDLES /* Putting max handles to lower than 32 will make pj_fd_set_t size smaller * than native fdset_t and will trigger assertion on sock_select.c. */ # define PJ_IOQUEUE_MAX_HANDLES 32 # define PJ_CRC32_HAS_TABLES 0 # define PJSIP_MAX_TSX_COUNT 15 # define PJSIP_MAX_DIALOG_COUNT 15 # define PJSIP_UDP_SO_SNDBUF_SIZE 4000 # define PJSIP_UDP_SO_RCVBUF_SIZE 4000 # define PJMEDIA_HAS_ALAW_ULAW_TABLE 1 #define PJMEDIA_RESAMPLE_NONE 1 #define PJMEDIA_HAS_SPEEX_AEC 0 #define PJMEDIA_HAS_VIDEO 0 #define PJMEDIA_CONF_USE_SWITCH_BOARD 1 #define PJ_DEBUG 0 Best Regards, Bernhard Am 27.01.2016 um 20:43 schrieb Ebubekir DEM?R: > Hi, > > I am try to using pjsua application in arm processor(ti am335x).
