             Summary:  Asterisk 11 svn branch and srtp - white noise only
                 Key: ASTERISK-21323
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-21323
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/SRTP
    Affects Versions: SVN, 11.3.0
         Environment: ubuntu 12.10 / 12.04 64bit
            Reporter: andrea
            Severity: Critical


Hi all,

 

we have just updated our Asterisk 11 testbed from 11.2.1 to 11.3.0-rc1. Now we notice that all sRTP calls fail with “white noise” in the media channel phone > asterisk.

 

Example 1:

 

Snom w/ srtp > asterisk > Yealink w/ srtp

Both ends hear “white noise”

 

Snom w/ srtp > asterisk > Gigaset w/o srtp

Snom hears Gigaset, Gigaset hears white noise.

 

There have been no other changes to the setup, SIP.conf  specifies

 

transport=tls

encryption=yes

 

for the sRTP phones.

 

Asterisk is linked to libsrtp 1.4.2.

 

Here is the log (that imho looks good):
