I think in the comment is a little typo ("unless this is a CANCEL > _on_ an ACK.."). I think, it should have been "unless this is a CANCEL _or_ > an ACK..". At least this is, what the code is doing.

We don't typically put issue numbers in comments, as the commit message should have the issue number referenced in it. The output 'svn blame' should help explain the issue that caused the code change. > On Dec. 19, 2014, 9:59 a.m., Scott Griepentrog wrote: > > http://svn.asterisk.org/svn/asterisk/branches/11/channels/chan_sip.c, lines > > 11840-11842 > > <https://reviewboard.asterisk.org/r/4279/diff/1/?file=69816#file69816line11840> > > > > Purely for readability, the sipmethod == SIP_UPDATE condition should be > > indented to the same level as SIP_ACK, since it is similarly nested under > > the same negation started on the line containing SIP_CANCEL. > > kwemheuer wrote: > OK.
