[asterisk-bugs] [JIRA] (ASTERISK-22942) asterisk crashed after Set(FAXOPT(faxdetect)=t38)

[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-22942?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=212679#comment-212679 ] 

Matt Jordan commented on ASTERISK-22942:
----------------------------------------

Patch looks correct, particularly since just prior to this point we break out of {{AST_FRAME_VOICE}} processing if {{faxdetect->dsp}} is NULL:

{noformat}
	switch (f->frametype) {
	case AST_FRAME_VOICE:
		/* we have no DSP this means we not detecting CNG */
		if (!faxdetect->dsp) {
			break;
		}
{noformat}

Thanks for contributing back the patch!
