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

             Summary: One-way audio, Asterisk not sending audio upstream.
                 Key: ASTERISK-26654
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26654
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
         Environment: CentOS x64 - No NAT, public IP
            Reporter: Luke Escude
         Attachments: 2calls.pcap, asterisk_debug

We have been struggling with random (very inconsistent) one-way audio phone calls for a couple of months now. 

This issue ONLY affects a few of my customers on a raw Asterisk installation, none of my FreePBX customers are having any issues.

The server is hosted in our datacenter with a public IP - no firewall, no NAT, and it trunks to Flowroute. The customer is behind NAT, however the system works just fine like this - we always have 2-way audio between customer and our server.

Attached is a PCAP of 2 phone calls that experienced one-way audio, and the console debug messages from asterisk.

Flowroute is pulling a packet capture of their side for me, as we speak.
