> Hello,
> In a case while a pjsip channel make a SRTP request to an endpoint and it respond with non srtp sdp, call was continued with non srtp mode but following dialplan function report srtp is on. 
> channel(rtp,secure,audio)
> We have made a quick review on dialplan codes and found,
> File:  channels/pjsip/dialplan_functions.c
> Method: channel_read_rtp
> Line 533: snprintf(buf, buflen, "%d", media->srtp ? 1 : 0);
> srtp status is reported only by checking an object initialization. I think if an endpoint unable to respond with srtp that object might not destroyed. Now can we use any flag to determine this status?
> Thanks,
> Salah Ahmed
