Hi all, I want to increase the number of simultaneous calls support in pjsip which is by default 4. I want to make it to 60 calls. for this I have already increased the PJSUA_MAX_CALLS to 64 and doing cfg->max_calls to 60 in the following funtion in pjsua_core.c. PJ_DEF(void) pjsua_config_default(pjsua_config *cfg) { pj_bzero(cfg, sizeof(*cfg)); *cfg->max_calls = ((PJSUA_MAX_CALLS) < 4) ? (PJSUA_MAX_CALLS) : 60;* cfg->thread_cnt = 1; cfg->nat_type_in_sdp = 1; cfg->force_lr = PJ_TRUE; #if defined(PJMEDIA_HAS_SRTP) && (PJMEDIA_HAS_SRTP != 0) cfg->use_srtp = PJSUA_DEFAULT_USE_SRTP; cfg->srtp_secure_signaling = PJSUA_DEFAULT_SRTP_SECURE_SIGNALING; #endif cfg->hangup_forked_call = PJ_TRUE; } After doing the these settings I am able to compile the code successfully but my application is not getting registered. Infact It is not sending any REGISTER packet to the server. Any Idea please why it is happening so .... Please help me out in this issue , Thanks in advance.... Regards: Ravi
