[asterisk-bugs] [JIRA] (ASTERISK-26654) One-way audio, Asterisk not sending audio upstream.

[Luke Escude (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-26654?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Luke Escude updated ASTERISK-26654:
-----------------------------------

    Description: 
We have been struggling with random (very inconsistent) one-way audio phone calls for a couple of months now. Out of the 10,000 phone calls we process per day, this only happens to less than 20 of them.

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.

New info: Calling her works flawlessly on FreePBX.
