[asterisk-bugs] [JIRA] (ASTERISK-29526) G729 audio gets corrupted by Asterisk due to smoother

[under (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-29526?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

under updated ASTERISK-29526:
-----------------------------

    Description: 
If Asterisk gets G.729 6-byte VAD frames inbound, then at outbound Asterisk sends this G.729 stream with non-continuous timestamps (see rtp.log attached).

After debugging, I found this is a regression connected with RTP Smoother (main/smoother.c).

Smoother has a special code to handle G.729 VAD frames (search for  AST_SMOOTHER_FLAG_G729 in smoother.c).

However, this flag is never set in Asterisk-12 and newer.
Previously it has been set (see Asterisk-11).
