--------------------------------------

             Summary: Incoming queued calls are occasionally  forwarded with wrong From: header
                 Key: ASTERISK-27744
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27744
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/General
    Affects Versions: 13.14.1
         Environment: Linux 4.9.0-6-amd64 #1 SMP Debian 4.9.82-1+deb9u3 (2018-03-02) x86_64
            Reporter: Janko Zgaga


With incoming calls forwarded to a static queue, I occasionally see wrong From: header on the call, once forwarded to the local extension (From: gets the same sip id as To:) You can find a log of one such call at http://www.itd.si/Buldozer/astlog.zip

There's more calls in there, but interesting one is the first one - Call-ID: BW0904004831603182087347519 at 172.18.1.14 (log continues until it's end). You'll see that a call, coming in from
From: <sip:027031065 at 192.168.213.126;user=phone>;tag=2026492818-1521187440483-

 gets forwarded to
To: <sip:01238471 at 192.168.1.108:5080;ob>

as
From: <sip:01238471 at 192.168.1.1>;tag=as7dc0234c

 ... numbers are (consistently) obfuscated

I have started seeing such calls from 2017-10-24, but can't really say which version of Asterisk it was back then. I update to latest debian stable releases on monthly basis so it should be a debian release from around that time. It seems to happen some 11% of the time. Do let me know if more info is needed.
