[asterisk-bugs] [JIRA] (ASTERISK-20784) Failure to receive an ACK to a SIP Re-INVITE results in a SIP channel leak

[NITESH BANSAL (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-20784?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=204126#comment-204126 ] 

NITESH BANSAL commented on ASTERISK-20784:
------------------------------------------

The issue was reported on 1.4 but was suspended because you guys had stopped looking at issues reported on Asterisk 1.4.
So the fix never became a part of Asterisk and the issue is still present in Asterisk 11.
