             Summary: peer is not matched to an IP address
                 Key: ASTERISK-22579
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-22579
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/Interoperability
    Affects Versions: 11.5.1
         Environment: debian 64
            Reporter: Private Name


My peer is behind a NAT. 
The peer definition is
[XXXX.YYY.ZZ.PPP]
type=peer
host=XXXX.YYY.ZZ.PPP
insecure=port,invite
directrtpsetup=no
directmedia=no
nat=comedia,force_rport

In spite if that, when I place a call, the bridging always shows "remotely bridging". This is wrong, so I started to investigate and found that when I have the call connected, and type
 Using SIP RTP CoS mark 5

The call drops after a few seconds because my peer never gets a packet.
If you look closely, "8.xx.245.xx      Asterisk         NGY0NzE5ZjBlNDI " this is the issue. The IP is that of my Asterisk server, not of my peer. It is not matching my peer to the IP address, thus, the NAT and media configuration are not being used.

If I set the server as a whole, in the [general] section to my nat and media restrictions, then it works fine. 
This means that something is broken with Asterisk 11, something that worked fine before.

I can give a developer access 24x7 to my server. He/she may send a call from behind a NAT. I will create a peer with the IP address, and the issue will be evident.
