Colleagues, please tell me what has changed and what is my problem! I took my code from about a year ago, that worked for me, and recompile it, updating the components of the operating system. After that, the problems started - the outgoing call is initialized, but after I pick up the phone on the phone receiving the call, the call is canceled. At the same time, strange messages appear on the application screen, clearly from the library: > *warning: discarded first playback frame > warning: discarded first playback frame > warning: Auto-filling the buffer (your application is buggy and/or got > xruns) > * The code for making an outgoing call previously worked for me and is taken from the example: > *pj_str_t uri = pj_str ("sip:100@pbx.mydomain.org"); >     status = pjsua_call_make_call (acc_id, &uri, 0, NULL, NULL, NULL); >     if (status != PJ_SUCCESS) >         error_exit ("Error making call", status);* I use > *FreeBSD 12.2-RELEASE-p7 GENERIC  amd64 > pjsip-2.11.1* How can I solve this problem? Thanks in advance for your reply, Ogogon.
