[asterisk-bugs] [JIRA] (ASTERISK-27397) SRTP call fails if transferred to unencrypted endpoint

[basildane (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-27397?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=240017#comment-240017 ] 

basildane commented on ASTERISK-27397:
--------------------------------------

I uploaded pjsip.conf as requested.

I also changed 207 to not have explicit transport=0.0.0.0-tls, in order to simplify testing.  The problem remains when 207 has the same "auto" setting as the other extensions.

> Call between two SRTP endpoints work ok until transferred to a device that does not have SRTP.  Then Asterisk logs:
> {panel}
> res_srtp.c: SRTP unprotect failed with: authentication failure 110
> {panel}
> Audio is lost from the call at this point.
