[asterisk-bugs] [JIRA] (ASTERISK-20499) Crash in libsrtp srtp_unprotect_rtcp when SIP channel is bridged with non-optimizing Local channel

     [ https://issues.asterisk.org/jira/browse/ASTERISK-20499?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

tootai updated ASTERISK-20499:
------------------------------

    Status: Waiting for Feedback  (was: Waiting for Feedback)

Sorry for the missing action concerning feedback, will remember now.

Dialplan to get core dump is easy:

exten => 800,1,Dial(Local/600 at demo,,) ;call echo test
exten => 800,n,Hangup

I replace this sequence with 

exten => 800,1,Playback(echo-test)
exten => 800,n,Echo
exten => 800,n,Playback(demo-echodone)
exten => 800,n,Hangup

and guess what, no more core dump!

So Local channel seems to be the cause. Have to stop to use it as I already have an open bug with him: ASTERISK-19763 ;-)

Thanks for your support, feel free to ask me if you want further details, logs or tests.

> A call from snom320 in SRTP mode to echo test or to another phone *NOT* using SRTP is OK. Now we installed PhonerLite softphone with TLS/SRTP stuf and test with echo test: everything is OK too.
> Now PhonerLite calls the snom: asterisk coredump after 3~5 seconds and we are NOT able to make anymore SRTP calls after this, they all crash asterisk. We had this issue with 10.7.0 and 10.8.0
> We have logfiel from strace as well as coredump.
