Hello,

is almost certainly a NAT problem.
Use something like pcapsipdump, take trace of all your calls, then when a call with one-way audio happens, look into its pcap.

Hi,

  Before I dig into this issue and start collecting data in order to open a Jira: Has anyone else noticed it? When I call or get a call sometimes there is one way audio. Hanging up and calling again usually solves it. It happens quite rarely, so I cannot reproduce it at will. However, it annoys the users...

I am running FreeSwitch 1.4.18 and use various phones (Polycom, Yealink, SNOM, etc.).

                  Thanks! __Yehavi:
