[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=239847#comment-239847 ] 

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

If it helps, most of my endpoints are pjsip.  The failure also occurs when the destination is sip (our exchange unified messaging server), or a DAHDI extension.
Also, I get "failure 10" in addition to "failure 110" in some scenarios.

> 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.
