    [ https://issues.asterisk.org/jira/browse/ASTERISK-22805?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=211439#comment-211439 ] 

Matt Jordan commented on ASTERISK-22805:
----------------------------------------

Your backtrace appears to come from an un-optimized version of Asterisk:

{noformat}
#1  0x00007f12f34daa14 in dtls_srtp_check_pending (instance=0x7f132402b7d8, rtp=<value optimized out>) at res_rtp_asterisk.c:1244
        pending = <value optimized out>
{noformat}

Are you sure you compiled Asterisk with DONT_OPTIMIZE? 

That aside - based on the backtrace, it looks like we're crashing when calling BIO_ctrl_pending:

{noformat}
	size_t pending = BIO_ctrl_pending(rtp->write_bio);
{noformat}

If you have the core file, it'd be very interesting to see what the value of {{rtp->write_bio}} is.

Can you attach your {{sip.conf}} to this issue as well? Did you configure {{sip.conf}} to support DTLS-SRTP?
