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

[Richard Mudgett (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-27397?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=239974#comment-239974 ] 

Richard Mudgett commented on ASTERISK-27397:
--------------------------------------------

The transport configurations are part of pjsip's configuration in {{pjsip.conf}}.  They are the sections with {{type=transport}} in them.  The 207 endpoint you supplied in [^pjsip.endpoint.conf] contains an explicit transport reference {{transport=0.0.0.0-tls}}.  The other two endpoints don't have an explicit transport so they are free to pick an appropriate transport.

> 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.
